Can monthly go after conception?


If the fact of pregnancy is confirmed, and the bleeding continues to go, an urgent need to run to the doctor. In any case, it is impossible to call it a norm. Even if he does not confirm the miscarriage during the inspection on the chair and ultrasound, it is useful to donate blood to determine the level of hormones and inflammatory processes.

Normal menstruation, which occurs due to hormonal disorders that can occur in a woman's body during the first months of pregnancy, is insignificant and not accompanied by pain. If bleeding started, accompanied by cramping pains in the lower abdomen, it can speak about the beginning of a miscarriage and save the child's life in this case can only call an ambulance, before arrival which you need to take a horizontal position and stop making extra gestures.

What to look for?

If you pay attention to the discharge, you can notice a big difference. Yes, with a convinced pregnancy and the arrival of menstruation at the end of the cycle, there are deviations in the body and you need to sound the alarm. But there are exceptions to the rule. The fact is that with the advent of menstruation, hormones are released, as a result of the influence of the brain on the endocrine system. It is under their influence that the egg is ready for fertilization, and the uterus is ready to receive the ovum.

The body of a young girl contains up to 2 million eggs, more than 400,000 mature ones. With the advent of each period, up to 20 cells mature in the egg, one of them, located in the bubble of grape, leads. In the process of ovulation, the cell moves into the uterus tube through the processes, approximately 24 hours remains viable.

On the first day of ovulation, women experience pain and discomfort. This is a signal about the conception of the egg, but the bleeding is not at all menstrual, but only smear, light red discharge, which lasts no more than 2 hours. May increase after sex, as a result of cervical stimulation, and this fact cannot be called pathology. The arrival of menstruation in the first week of pregnancy, according to obstetric week, and this is normal. Conception is not yet, but it will overtake later, closer to the 3rd week.

Spotting can be considered ovulatory due to a rupture of the follicle in the ovary and the release of the egg out. When blood vessels are damaged, the blood can migrate to the peritoneum, the ovary will experience apoplexy, but the condition is not dangerous, not threatening the woman and the fetus. Discharges may also occur at week 3 at the time of embryo attachment to the endometrium of the uterus. It is said that the monthly went through the fruit. The arrival of bleeding associated with the onset of pregnancy.

There are cases when 2 eggs mature at once. One is fertilized, the other dies off, comes out accompanied with bleeding, and even at the time of conception come menstruation.

Monthly at conception are due to rapid restructuring of the body, if fertilization occurred in the middle of the cycle. They simply follow the usual pattern, if the fertilized egg does not have time to attach at the beginning of menstruation.

A lack of estrogen in a woman’s blood leads to menstruation. Hormonal failure happens, and women often learn about pregnancy only in 12-13 weeks.

If it's a miscarriage?

When confirming the fact of pregnancy and bleeding, contact with a doctor should be prompt. This condition is not the norm, and in the case of an unconfirmed diagnosis - miscarriage based on ultrasound results, it is recommended to pass an additional analysis for hormones. Possible inflammatory processes in the body.

If there are hormonal disorders, then in the first two months of pregnancy, normal menstruation can take place, but the discharge is insignificant and short.

When miscarriages appear cramping, severe pain, along with the usual bleeding during planned periods. To save the life of a kid, you need to call an ambulance as soon as possible. Waiting for her to lie down, without making unnecessary body movements.

Pregnancy, signs

At the very beginning of pregnancy, implant bleeding occurs, and this is the norm. A woman is hardly aware of her interesting position. Bleeding passes before the test shows 2 strips. This is due to the time of attachment of the ovum, usually falling on ovulation days, in the middle of the cycle. With a cycle of 30 days, this happens from 14th to 16th day. A fertilized egg moves to the uterine cavity through pipes from 10 to 14 days, penetrates the walls from 24 to the 27th day of the cycle. After 2-3 days, the planned monthly period should begin and this bleeding is real during pregnancy, not dangerous. These are the physiological features of the female body.

If women do not expect pregnancy, they do not always attach special importance to secretions that appeared earlier than the prescribed period. However, when planning a pregnancy, it should be understood that only implant bleeding is normal at an early stage of pregnancy, at the time of its inception.

It is important for every woman to learn how to distinguish vaginal bleeding from others. Unfortunately, untimely periods are often not associated with pregnancy, but with inflammatory processes, infections, diseases occurring in the body, which need to be treated as a matter of urgency. Learn to recognize the nature of bleeding. For a woman of child-bearing age and planning children, this is extremely important.

When are bleeding dangerous?

Many women fear miscarriages when blood is released more than 24 hours after conception. No need to panic, it is better to see a doctor. The probability of a threat is there, but the cause of prolonged bleeding may be completely different. For example, the inflammatory process in the body, failure of many systems and organs.

The consequences are unpredictable with ectopic pregnancy. This is a serious complication. When implantation of a fertilized egg outside the uterus, discharge, similar to menses, begins. In fact, this pathology leads to rupture of the fallopian tube. In some cases, with timely access to a doctor you can cope with this pregnancy. When a problem is triggered, sometimes a surgical intervention can no longer be done. If the bleeding does not go away or appeared at the end of the menstrual cycle and the girl is sure that she is pregnant, then you need to visit a gynecologist. Possible serious abnormalities in the body.

There is no threat if daub with small secretions occurred at the beginning of pregnancy due to the onset of menstruation. This is a symptom, rather than a disease.

It is important for every woman to understand the reasons that provoked the appearance of discharge, bleeding if the test result is positive. A timely visit to the gynecologist will help to avoid many problems. Sluggishness is in most cases harmful when menstruating during pregnancy. However, bleeding is normal, occurring during pregnancy, it happens in rare cases. Do not expose the life originated inside you. Contact your doctor if you suspect a malfunction in the body. Hormonal failure is unstable, begins to rebuild at conception. Symptoms of pregnancy may in fact be very diverse.

Is it possible?

Can monthly go after conception? In most cases, after conception, the menstrual periods cease, a temporary gland responsible for this is the yellow body of the ovary. It produces the hormones necessary for proper implantation and development of the fetus. But there are cases when a woman finds out that an embryo develops in her body only after the first stirring or the appearance of other signs of pregnancy, since she had monthly periods every month. Sometimes such a pregnancy develops quite normally against the background of menstruation, therefore it is impossible to completely deny its presence, if all other signs confirm this fact.

Basically, a pregnant woman can go for periods due to the fact that conception occurred in the middle of the cycle, in this case, the egg does not have time to implant to the wall of the uterus and in the body does not occur hormonal adjustment. Also, the cause of failure can be such a rare phenomenon as the continuation of the production of eggs after fertilization of one of them. Bleeding at the same time are minor, but regular. Monthly during pregnancy is also possible due to insufficient production of estrogen. This pathology occurs quite often, in this case, the woman learns about her pregnancy closer to 12 weeks of gestational age.

One of the unlikely causes of menstruation during pregnancy is hormonal failure. When two oocytes come out at once and can be fertilized during one cycle. The egg cell can fertilize against the background of menstruation. Therefore, the calendar method of protection is very unreliable, everything in the body is controlled by hormones, and it is necessary for the pituitary to give the appropriate signal as a new egg comes out of the ovary.

Why is this happening?

Some women may experience discomfort during ovulation. This may indicate that egg fertilization has occurred. Blood clots do not mean the arrival of menstruation, their duration does not exceed 2 hours. Pain and bleeding may start or worsen after sexual contact due to irritation of the cervix, this is completely normal.

Monthly in the first week of pregnancy means that the egg has not yet been implanted, so the conception has not yet happened, it will be a little late. There are also cases when two oocytes mature and leave at once. One is fertilized by the sperm, and the second dies off, the bleeding occurs as a result of its rejection. The arrival of menstruation does not affect the course of pregnancy developed from the second egg.

Monthly during pregnancy are usually only in the first month. Why it happens? Because the fertilized oocyte moves to the site of implantation, but the hormonal response will occur only after the embryo attaches to the wall of the uterus. Therefore, the cessation of menstruation will follow in the next cycle, when the embryo takes its place in the uterus and hormones change in the woman's body. This is a typical course of events when fertilization occurs in the middle of a cycle.

How to distinguish menstruation from miscarriage?

It is almost impossible to determine whether it is monthly or a threat of miscarriage. When hormonal failure can be menstruation during pregnancy, it usually occurs with scanty discharge and only in the first month of pregnancy.

In the absence of any delay, it can be considered with almost certainty that these are ordinary periods. But if the menstruation was delayed for at least a couple of days, then most likely fertilization and miscarriage occurred. A characteristic feature of a miscarriage is profuse and painful bleeding, which has a longer duration. Discharges are often bright red, sometimes brownish.

After an early spontaneous abortion, the discharge contains remnants of the membranes of the fetus in the form of blood clots. If the general condition of the woman is not disturbed, then she will most likely refrain from visiting a doctor. If, during a miscarriage, you experience cramping abdominal pain radiating to the lower back, an increase in body temperature, a significant deterioration in health, nausea, weakness, dizziness, you should immediately go to the hospital. This indicates that the fetal membranes are not completely out and that the woman needs curettage of the uterus.

It is impossible to distinguish a miscarriage from ordinary menstruation by external signs, and an ultrasound examination a week after fertilization will not work. On this date, the fertilized egg is still too little. A gynecological examination will also not be informative, since palpation and internal examination of the cervix will not allow to establish the presence of pregnancy. The uterus can be slightly enlarged in any case, both during pregnancy and after miscarriage.

When is it worth to see a doctor?

If after conception went monthly, it is necessary to visit a doctor. If the fact of fertilization is accurately established, the bleeding can provoke any physical activity, infectious processes and injuries. In this case, before the arrival of the ambulance, the woman should take a horizontal position and relax.

With a significant deterioration of health, accompanied by vaginal bleeding and spastic pains in the lower abdomen, it is necessary to exclude the presence of ectopic pregnancy. This is a very serious complication that can cause abundant internal bleeding. Localization of pain can be spilled or unilateral. A woman may have orthostatic fainting from blood loss, pain in the shoulder due to irritation of the phrenic nerve due to internal bleeding, pressure in the rectum or bladder.

Conclusion and conclusion

Monthly and pregnancy are not mutually exclusive states, but they occur quite rarely. It is important not to be frivolous about any unusual phenomenon during a reliably established pregnancy, timely referral to a specialist can save the fetus, even if bleeding has already begun. Monthly during pregnancy is possible in the first month after fertilization, but they are short and not abundant.

Abdominal pain, bleeding and fainting may indicate an ectopic pregnancy, which is fraught with a ruptured tube. This is a serious condition requiring emergency surgical care. If small bleeding appeared in the first days after fertilization, then they mean implantation of the embryo and are absolutely normal.

Can pregnant women go monthly

Almost all women are convinced that the next menstruation means that fertilization has not occurred. If a girl is afraid of pregnancy, she is looking forward to the beginning of a new cycle, when menstruation comes. And here on the clothes are spotted bloody specks, indicating the arrival of regular menstruation. A woman lives the old life, without changing habits, menstrual bleeding comes regularly. And then the girl notices the obvious signs of pregnancy, buys the test and is surprised to find that she will soon become a mother. The doctor confirms the pregnancy, and already with a solid 8-12 week period.

Such cases are found in gynecological practice all the time. Sometimes it happens that menstruations go up to 16 weeks after conception, when it will be impossible to have an abortion at will. This is often observed in obese women with a big belly. They simply do not notice that their belly begins to grow, and when the pregnancy becomes very mature, it remains only to give birth. Why is this happening? It's all about physiology.

Physiological features

The female body functions according to a specific cycle.

  • Every girl at birth in the ovaries lays a certain number of eggs, which during life must mature and, possibly, fertilize.
  • Every month during the ovulation period, one of the eggs matures and leaves the follicle, moves into the tube for fertilization.
  • If conception does not happen, then the cell dies and leaves in the composition of the menstrual bleeding.
  • The uterine cavity from the inside is covered with endometrium. This layer functions, completely dependent on hormonal processes. After menstruation, it begins to grow rapidly. The role of endometrial tissues is to provide the baby with the necessary nutrition, so the endometrium is well supplied with blood, and when it is peeled, there is marked bleeding.
  • In the absence of implantation, a signal is not sent to the brain to develop the corresponding hormonal complex, as a result, the endometrial intrauterine layer is rejected and goes out with blood.
  • In fact, when menstruations begin to go, the processes of exfoliation of the inner layer in the uterine cavity are launched. The hormonal system of the patient is actively involved in this process.

If conception has occurred, the egg is implanted in the endometrial layer, while the hormonal picture of the body changes radically - progesterone begins to stand out, contributing to thickening of the uterine walls, compaction and growth of endometrial tissues so that the embryo can firmly secure to them. In addition, progesterone does not allow the uterine walls to shrink so that they do not reject the foreign body, which is the fetus.

Let us return to the main question - can the monthly ones go shortly after conception? In general, this is impossible, although sometimes there are exceptions. But most often girls confuse menstruation with bleeding.

Why can there be bleeding during gestation?

Some bleeding is safe for the fetus and gestation in general, while others can lead to dangerous consequences, so this feature requires the mandatory identification of the causes. Better safe than losing time and losing a child. In general, bleeding in the first weeks of gestation can begin for several reasons. One of these are hormonal disorders. In such situations, menstruation is poorly, have a smearing character, and at night there is no selection at all. Для выявления причины и устранения проблемы необходима консультация гинеколога и эндокринолога, которые подберут препараты, безопасные для плода и вынашивания.

With the threat of interruption, the girl can also detect signs of menstruation, only this is not menstruation, but bleeding, which is accompanied by painful sensations, like contractions or heaviness in the stomach. In this situation, there is only one sure way - to urgently call an ambulance. In addition, bleeding during gestation is a common ectopic symptom. With this pathology, the painful symptoms bother in a particular place where the embryo has entrenched. In general, the pain is constant, although they may disappear for several hours or days, but soon resume. In late terms, the pain syndrome may intensify to unbearable sensations. The problem is eliminated surgically.

If a woman with a bear or before it caught any infection, then it is likely that she, too, will go monthly. The situation is complicated by the difficulty in choosing medications, because far from all drugs are allowed for pregnant women. Quite often, the cause of bleeding after conception is implantation. It is not even bleeding, but only a slight dark-colored daub, because the blood coagulates even inside the uterus. For implantation bleeding is characterized by scarcity and short duration.

Attention! A particularly alarming sign is the appearance of scarlet heavy discharge. In such a situation, urgent medical intervention is necessary. The more blood a pregnant woman has lost, the more critical the picture of the pathology is, even if there is no painful symptoms.

Sometimes there are situations when the patient becomes pregnant with twins. Under the influence of any factors, the death of one fetus occurs. When it is rejected, the bleeding will open. In such a condition, the woman should be under the strict supervision of obstetricians in order to prevent adverse consequences for the second, surviving child in a timely manner. Also, monthly bleeding can begin in pregnant women who have structural uterine pathologies such as myoma formations, endometriosis, etc.

Color pregnancy

In gynecology, there is such a thing as color pregnancy, which means the presence of menstrual flow after fertilization. Many doctors admit the likelihood of having menstrual periods in girls in the first few cycles after conception. But they have their own explanation. First, such menstrual flow may be the result of failures of the menstrual cycle, as a result of which abundant or scanty discharge may appear after conception.

When carrying out, when menstruation begins, the patient, as a rule, does not observe the traditional symptoms characteristic of ordinary menstruation. She has no headaches, fatigue, drowsiness and some irritation, swelling of the mammary glands, etc. If the pregnancy was planned, there were unprotected sexual intimacy in the favorable period for conception, and at the beginning of the cycle several unusual menstrual periods began. for the presence of pregnancy. Spotting test results will not be able to distort the test, but it is even possible to exclude or confirm a probable pregnancy in this way.

Bleeding or menstruation?

Can there be monthly periods for pregnant girls? Experts warn that the presence of bleeding during pregnancy can not be regarded as the norm. This sign indicates a violation in the hormonal sphere. During a gynecological examination, prerequisites for interruption or miscarriage that has already occurred may be found. Pathological bleeding from menstruation can be distinguished by red blood and abundant secretions.

Also, a distinctive feature of bleeding is the presence of pain, which may be sharp and sharp, or be pulling and dull. It is precisely by such signs that pathology can be suspected and urgently called an ambulance.

In practice, there are many cases when a woman finds out about conception only from a growing tummy, while the monthly periods during pregnancy seem to be absent altogether. But this is not a pattern, but rather an exception, which is silly and even dangerous to hope for. Most often, a woman with such bleeding has to lie in the gynecology for months to save the baby and keep the pregnancy. Therefore, with the appearance of blood from the vagina, regardless of the amount of discharge, you should consult with a specialist.

Are menstruation dangerous during pregnancy?

It is difficult to immediately determine how dangerous the bleeding is. Not all secretions containing blood can threaten the life of the child and the patient herself. Therefore, a pregnant woman herself must soberly assess her condition and the situation as a whole. If bleeding is observed that resembles menstruation in intensity and duration, then in almost 100% of such cases the patient loses the child. A similar outcome is expected when overly painful bleeding occurs.

With scanty, spotting secretions, even with their regularity, there is usually no threat to the fetus, but you will still have to turn to the doctor, if only to make sure that there is no threat. There are cases when the monthly went regularly throughout the pregnancy, which ended in successful delivery, but such situations are few. Usually such cases are explained by the memory of the organism, due to which the usual hormonal background is created, as before pregnancy, which can become critical for the baby. Although in general, in the early stages, the monthly periods are not dangerous for the fetus.

How to be with the appearance of such discharge?

What should a woman do when faced with a similar phenomenon?

  1. The first step is to make sure you have a pregnancy, if you are not already registered in gynecology. To do this, you can do home strip test. If the fact of conception is confirmed, then you need to contact a specialist.
  2. If the doctor has already confirmed that the pregnancy is taking place and bleeding has begun, then an urgent need to run to the antenatal clinic. They assign the necessary laboratory tests and conduct an ultrasound scan that will help determine the cause of bleeding.
  3. If you are sure that you are expecting a child and you are not bothered by the sudden sharp pains in the uterus (lower abdomen above the pubis), which are given in the lower back and back, you must call an ambulance. In the presence of a similar symptom complex (bleeding + sharp and sharp pains) the probability of a miscarriage is high. With correct and timely actions, doctors will help to keep the pregnancy, but for this you need to ask for help immediately after the appearance of the first pathological signs.

Menstruation mechanism

To better understand the essence of the issue, you should be well aware of how regular menstruation occurs. In the first half of the menstrual cycle, the uterus begins to acquire additional membranes that thicken its endometrium.

During ovulation, the finished and mature egg leaves the follicle on the ovaries into the fallopian tube. If there is a meeting with sperm, pregnancy will come. If there is no such meeting, then the egg cell will die in a day and descend into the uterine cavity.

The uterine membranes, enlarged over the cycle, in the absence of pregnancy as superfluous are simply removed from the body outside in the form of menstrual bleeding. If the pregnancy comes, everything changes.

Changes in the body after conception

After fertilization of the ovum by the sperm cell in the woman’s body, a mass of various processes immediately start to preserve the pregnancy. The hormonal background changes, large concentrations of progesterone begin to be produced. This sex hormone prepares the uterus for the upcoming implantation of the ovum, the endometrium of the female reproductive organ becomes thicker, friable. The hormone suppresses immunity, so that the accidental germ, which by 50% is only akin to the female body. The child inherited the second half of the genetic material from the father.

Progesterone relaxes the uterine muscles. About a week after fertilization, the blastocyst, which has become a fertilized egg, descends into the uterus and attaches to one of the walls, tightly in contact with the endometrium. It practically grows into the wall of the uterus. From this moment on, the hormone hCG, a human chorionic gonadotropin, begins to be produced. It was he who combined with a high level of progesterone leads to a delay in the next menstruation.

The baby grows and develops in the womb within 38 weeks. By the end of the first trimester of pregnancy, hCG levels peak and begin to decline, and progesterone begins to decline closer to childbirth. Actually, its decrease to a certain concentration causes the generic process itself.

In 95% of women, this is exactly what happens. But there are also such pregnant women who can for a long time not guess about their “interesting” position, because they have periods. And only the growing uterus and other symptoms will put everything in its place.

Causes of menstruation after conception

The normal occurrence of menstruation after conception is rather difficult to count. There is an opinion among the people that menstruation after a delay is a sign of the so-called “ablution of the fetus”. Doctors do sometimes come across such a phenomenon, and it can be quite difficult to explain it.

But normally this happens only once - in the first month of pregnancy. In the future, any bleeding will be considered a threat of abortion.

A slight bleeding, resembling menstruation, may occur after conception in about two weeks., that is, in the period of the next menstruation in the event that a woman has a two-horned uterus or, in this cycle, two eggs are released from the follicle during ovulation and only one is fertilized. Next month there should be no such discharge anymore.

If the pregnancy test showed two strips, and the next day or a few days later the woman started menstruating, it can speak not only about the release of the second, “unnecessary”, dead egg, but also that the fertilized egg could not properly implant and rejected. There can be many reasons: chromosomal abnormalities of the embryo, which made it impossible to continue its normal development and growth, exposure to toxins, gynecological diseases, which include endometriosis and other inflammatory and infectious diseases.

The cause of unscheduled menstruation after conception may be a failure in the woman's menstrual cycle. If ovulation occurred late, then it is possible that at the time of the arrival of the monthly implantation is not yet complete. This happens very rarely, but a woman should be aware of this possibility.

However, in most cases, for menstruation, a woman accepts other secretions that are also bloody. There are some situations in which a woman may experience such discharge after fertilization.


At 7-8 days after ovulation, a woman may begin a slight bloody or blood-like daub. She does not speak about pathology, but rather is the very first sign of pregnancy a week before the delay. The implantation of the endometrium is impaired during the implantation of the ovum, which may appear as insignificant and non-intensive bloody or yellowish secretions. At first, a woman may well take such a phenomenon as an early onset of menses, to think that a “failure” cycle has occurred.

However, this “menstruation” unexpectedly ends the next day or the next day. This convinces a woman that she "definitely failed." However, test strips in 7-10 days show confident and bright two strips.

Implant bleeding is not always the case and not every woman. Quite often, this delicate and delicate process takes place completely unnoticed for the future mother's state of health.

Hormonal disorders

Discharge, similar to the monthly, but only much more scarce and short, can go after conception due to hormonal deficiency. Progesterone deficiency, low levels of hCG and other metabolic imbalances may well lead to bloody discharge in the early stages.

It is noteworthy that the main danger of hormonal insufficiency lies not even in atypical discharge, but in the threat of spontaneous abortion.

A woman necessarily needs medical assistance. Treatment will be aimed at filling the deficit, hormone therapy will help save the pregnancy and save the expectant mother from bloody frightening secretions.

Cervical trauma

After conception, the mucous membranes become loose and vulnerable, the vessels become thinner. Spotting may occur due to injuries to the vagina and cervix. This happens after sexual intercourse or gynecological examination.

Discharge from the genital organs are not long-lasting and do not pose a threat to the life and health of the child.


Discharge, accompanied by pain cramping nature, in the early stages indicate a threat to the life of the fetus. This means that the ovum has rejected, died, or is close to death. In the secreted blood clots are clearly visible.

Without medical care in this case is not enough. If fragments of the embryo remain inside, an inflammatory process will develop, which may be complicated by sepsis. The only way out is surgery.

We also recommend to get acquainted with additional information on how to distinguish miscarriage from menstruation.

Bubble skid

The embryo has a temporary envelope (chorion), which is later converted to the placenta. It can mutate in the uterine cavity, expanding into a special tissue, similar to clusters with bubbles, which increases in size, resembling a tumor, and sometimes turns into a malignant tumor. To carry a child with such a diagnosis is impossible.

To remove the skid, the patient is anesthetized, the cervix is ​​dilated and the contents are scraped out. As a result of surgical treatment while preserving the reproductive organs of a woman, it remains possible to become pregnant after restoring the menstrual cycle.

Changes in the body after fertilization

Usually, in order for the fertilized egg to reach the place of its implantation from the fallopian tubes, 2-3 days are sufficient. But it happens that the process stretches a little longer - up to two weeks. In the case of conception before menstruation (which still happens due to the specificity of the cycle of a certain woman and contrary to popular belief that this is impossible), the egg simply does not have time to gain a foothold, and the brain - to receive a signal about the beginning of pregnancy. In this situation, critical days may well come at the appointed time.

When the zygote already grows to the wall of the uterus, and the placenta is activated, due to an increase in progesterone synthesis in the body, a change in the hormonal level is observed. It entails a number of other processes, including the cessation of menstruation. However, there is such a thing as “implant bleeding”. These are minor bleeding that are an early sign of pregnancy. They arise due to damage to the blood vessels at the time of attachment of the fertilized egg to the wall of the uterus. Many women easily confuse this discharge with the onset of menses.

Causes of menstruation after conception

As it was already found out, the two most common reasons for the arrival of critical days after fertilization of an egg are the incomplete process of insertion of a fetal egg into the endometrium of the uterus or the period of implantation of the blastocyst itself. Also monthly after conception can go into effect:

  • Hormonal disruptions when observed t. N. progesterone deficiency, estrogens are poorly produced, or there is an overabundance of androgens. In such cases, the body is simply unable to “recognize” the pregnancy, so the menstruation continues for some time in the usual way.
  • Simultaneous maturation of two eggs in each ovary, one of which is found with the sperm (that is, fertilization occurs), the second - is killed and excreted naturally.
  • “Colored pregnancy” is a rather rare phenomenon, during which several weeks, or even months, menstrual periods after fertilization, the egg still continues to go. But in this case, there are no symptoms, characteristic of the beginning of critical days: swelling of the body, breast enlargement and its sensitivity, pulling pain in the lower abdomen, changes in the emotional background.

In addition, spotting may be caused by cervical erosion, this is not menstruation, but bleeding. In such a situation, you will need a gynecological consultation to prescribe the correct treatment without the risk of threatening the fetus. Short-term bleeding, which women take for scanty menstruation, can be triggered by gynecological examination, sexual intercourse, douching. Среди прочих факторов медики называют простудные заболевания, сильные потрясения и стрессы, перенапряжения. В любом случае – определить точную причину менструации при беременности сможет только врач.

Когда после зачатия эндометрий матки отслаивается и начинается кровотечение, речь может идти о следующих патологиях:

  • самопроизвольный выкидыш,
  • ectopic, missed, mismatched pregnancy,
  • abnormalities in the structure of the uterus, in which the fetus is not possible to bear, because the embryo is attached in places with weak / absent blood supply,
  • placental abruption, placental presentation,
  • endometriosis, benign neoplasms of the endometrium, myometrium,
  • genetic pathology in the mother or the embryo, etc.

How to identify pathological disorders

In the early stages of pregnancy it is almost impossible to distinguish between ordinary menstruation and bleeding - evidence of the development of the pathological process. Therefore, a woman should be extremely attentive to the smallest alarming symptoms, signaling the danger to the fetus and the very future mother. Among them:

  • the abundance of secretions
  • the blood is bright scarlet
  • excessive abdominal pain, the nature of which can be from acute to pulling,
  • increased heart rate
  • jumps in body temperature,
  • general weakness
  • nausea, vomiting,
  • dizziness, migraines, etc.

If you find yourself with similar symptoms, you should immediately consult with your doctor. After all, bleeding, which are accompanied by cramping pains, can talk about the beginning of a miscarriage, and only an emergency call can save a pregnancy. Before the arrival of the doctors, it is imperative to take a horizontal position and try to eliminate unnecessary gestures.

In which case you need to consult a doctor

How dangerous can be the critical days after conception, it is difficult to determine at a glance. Not all spotting poses a threat to the lives of the mother and child. Sometimes menstruation is due to hormonal disorders that can occur in the female body in early pregnancy. In this case, they are smearing and not accompanied by pain.

However, if the intensity and duration of bleeding are similar to the usual menstruation, this is the first sign of a possible abortion. Too painful bleeding can also be a precursor to a similar outcome.

If they go monthly after conception, regardless of whether they are scanty or abundant in nature, a pregnant woman should immediately contact a gynecologist. Independent attempts to cope with bleeding with medications or folk remedies can result in serious health problems, including spontaneous miscarriage.

To establish an accurate diagnosis, the doctor will prescribe a number of studies, including:

  1. Ultrasound diagnostics to detect the presence in the uterus of the ovum.
  2. Blood chemistry.
  3. A test that determines the level of human chorionic gonadotropin, etc.

Opinion of doctors

Menstruation after conception, in its usual sense, can take place in the first month after fertilization. It takes a short time, while the discharges themselves are not abundant. Daub, appeared in the first days after conception, should not cause alarm. It is merely evidence of the implantation of the embryo.

It happens that the critical days continue to come regularly during the pregnancy. If the girl's state of health does not cause any complaints, and there are no abnormalities in the development of the fetus, medicine writes off a similar phenomenon to the body's memory, due to which the usual hormonal background takes place. It should be understood that these cases are rare.

Unfortunately, hormonal disorders in women are not uncommon today, because critical days can really come after conception. But even if the girl is sure that they will not harm the embryo, it is still worthwhile to consult with the gynecologist, since in the early stages of pregnancy it is difficult to distinguish between menstruation and uterine bleeding.

Menstruation or bleeding?

There are a lot of reviews from happy mothers who didn’t suspect their position until the moment when the belly began to grow. Many doctors can also recall cases from the practice when a woman had her menstruation almost the last month - and after that a healthy baby appeared, and the birth process itself went without complications. This is undoubtedly inspiring, but it is also worth remembering about women who have been forced to lie for several months because they did not pay attention to an alarming symptom in time. Here are some good reasons why bleeding can begin after conception:

  • critically low levels of hormones in the body,
  • miscarriage,
  • inflammatory process in the urogenital system,
  • threatened miscarriage
  • developmental pathologies of the uterus,
  • rejection of one of the fruits during the initial development of twins,
  • implant bleeding,
  • extrauterine development of the fetus.

Important! The bleeding during childbirth may not bring serious harm, but the first thing the expectant mother should do is to go to the gynecologist and ask for directions for the necessary research. It is better to be safe and find out the problem in time than to spend much more time and energy on treating the mother and child.

About the causes and consequences of bleeding during pregnancy

So, we figured out whether there can be monthly during pregnancy. But why do they start and is there a way to prevent it? We have already presented a short list of possible symptoms, and now we will reveal it in a little more detail.

  • Violation of hormonal levels.

Menstruation can be quite scanty, mostly “smearing”, and at night, blood, as a rule, does not flow at all. The solution to the problem in dealing with an endocrinologist and a gynecologist: they must pick up such drugs that do not harm the fetus. In more serious cases, it may be necessary to terminate the pregnancy for medical reasons (an extreme measure, appointed when it is completely impossible to bear and give birth to the baby).

The blood is scarlet and there is a lot of it. Abdominal pain is noticeably worse, many patients describe their feelings as “periodic strong contractions” or a constant feeling of heaviness. There is only one way out: urgently call an ambulance and prepare a bag for the hospital - even if the fetus cannot be saved, a woman may have complications that can be treated only in the hospital.

  • Ectopic fetal development.

Menstruation is also not abundant, but the pain, as a rule, is constantly localized on one side. The constant nature of the pain, they may disappear for several hours or even days, but they constantly return. In the later periods, the pain intensifies so much that the woman cannot tolerate them - it’s true, it rarely comes to that, because an ectopic pregnancy is diagnosed almost at the first ultrasound. The treatment is extremely quick, but you should not worry: even in advanced cases, when surgeons have to completely remove one of the fallopian tubes, the patient has a chance to become a mother again.

The choice of medications is highly dependent on the time and condition of the patient. The doctor should take into account all the little things, gradually stopping the bleeding and prescribing drugs that allow to stabilize the state of the body by introducing the necessary substances for its functioning.

Absolutely not scary, as a rule, it seems to be a few drops of blood on linen or smearing secretions of non-scarlet color (often it happens if the usual monthly periods for a woman are very abundant). Due to the short time from conception to the next menstruation. The fertilized egg is completely immersed in the endometrium, as a result of which a small amount of blood is secreted. Treatment does not require, but the patient is worth the first two weeks to actively monitor their condition.

The above reasons for preserving menstruation during gestation can be classified in different ways, but the main alarming symptom requiring early medical intervention is scarlet discharge in large quantities. The more blood is released, the more critical the situation, even if strong pain is not observed at this moment.

  • Pathology of the structure of the uterus.

For example, endometriosis or fibroids can also cause moderate bleeding during pregnancy. Drug treatment is prescribed, in advanced cases it is necessary to agree to surgery with a possible abortion.

  • Rejection of the second fetus.

If a woman became pregnant with twins, but at the very beginning of the development of one fetus died, rejection may begin, accompanied by slight bleeding. The process may not hurt the second child, but hospitalization and the supervision of a specialist in this case are required.

Diagnosis of pregnancy

If the absence of menstruation is not necessary, how can you diagnose pregnancy? Doctors advise women to listen to their own feelings. Already in the third week, a pregnant woman can feel:

  • breast tenderness
  • not too much pain in the very bottom of the abdomen, more like weak spasms.

At the same stage, the implantation bleeding described above can proceed. Of course, the result will not be accurate until the use of more modern methods, such as rapid tests and visits to the gynecologist. More specific symptoms, such as nausea in the morning, may appear later - from about the fifth to the sixth week, although there were cases when the only unpleasant symptom was a growing belly and legs swelling at the very end of the term.

Conclusion on the topic

If you do not ignore the obvious signals of the body, pregnancy will go well, and eventually a healthy baby will be born, even if at the beginning the joy of future motherhood was clouded by the presence of menstruation.

The main thing is to understand: if menstruation started to go even in the first month, this is far from the norm, and the best solution would be to consult a specialist, without using any available medicines. All that a woman can do in critical cases is to call an ambulance.

Until delay

A few decades ago, women assumed the onset of pregnancy due to the absence of regular menstruation, pregnancy tests or human chorionic gonadotropin (hCG) were inaccessible and far from being so accurate. Then the women, after several weeks of delay, went to see a doctor, who, having felt the already enlarged uterus during the examination, stated the pregnancy in terms of about 7-9 weeks.

Now pregnancy tests can be bought at every pharmacy or supermarket, they are accurate and sensitive enough. Good tests with a high content of reagent can react to pregnancy even before the onset of a delay, that is, 2-3 days before the expected menstruation.

So women learn about pregnancy at short notice. On the one hand, this is good, because patients with certain health problems can start taking any medications in advance, or vice versa, cancel dangerous drugs. On the other hand, such an “overdiagnosis” leads to unnecessary actions on the part of the woman and doctors and setting completely unnecessary diagnoses.

The bleeding from the genital tract at the time of menstruation against the background of pregnancy confirmed by the test can still be attributed to menstruation, since such a pregnancy did not have time to implant.

After conception

Some women know the exact date of conception, for example, they calculated their ovulation according to the temperature schedule or ovulation tests. Sometimes a week after conception, the patient may observe "menstruation." As a rule, it is scant spotting or brownish mucus that lasts 1-2 days.

This phenomenon is called implant bleeding - the destruction of the uterine mucosa by the fertilized egg invading it. Implant bleeding is a variant of the norm and characterizes the normal implantation of the embryo into the uterine lining. This is the only option when conception and “monthly” are connected with a positive moment.

During pregnancy

In more significant periods of pregnancy - 7-16 weeks - bleeding from the genital tract is the first and main sign of the beginning of an abortion. This is called a threatening spontaneous abortion, a spontaneous abortion that has begun, or an abortion is in progress, depending on the intensity of the bleeding and the presence of signs of life in the fetus.

Such bleeding does not occur because of the rejection of the uterine mucosa, but because of the detachment of the ovum or chorion from the uterus wall, rupture of the feeding vessels and the formation of blood or hematomas.

In gestational periods of more than 16 weeks, when the placenta or the infant's place has completed its development at the site of implantation of the ovum, bleeding from the genital tract is a sign of detachment of this placenta from the uterine wall. This is one of the most dangerous complications of pregnancy. In such terms, bleeding becomes dangerous not only for the fetus, but also for the woman herself.

In the third trimester, bleeding from the genital tract can also occur due to damage to the umbilical cord vessels in the fetus or their separation from the placenta.

The most common cause of bleeding during pregnancy, especially in its early stages, are certain hormonal disorders:

  • Lack of progesterone or hormone second phase of the menstrual cycle.
  • Disorders of the thyroid gland - its increased function (hyperthyroidism) or decreased function (hypothyroidism).
  • Excessive secretion of the pituitary hormone - prolactin.

In addition to hormonal disorders, some patients have abnormalities in the blood coagulation system. The most frequent of them are:

  • Thrombocytopenia - a decrease in the number of platelets,
  • Various genetic defects of coagulation factors - von Willebrand disease, vitamin K deficiency and others.
  • Antiphospholipid syndrome or APS.
  • Other thrombophilia.

Such disturbances in the endocrine and coagulation systems can both cause minor hemorrhages in the early stages, and heavy bleeding with loss of pregnancy.

Ectopic pregnancy

Normally, a fertilized egg should get out of the fallopian tube into the uterus, implanted in its wall and continue its development. However, in some cases, the fertilized egg remains in the fallopian tube or migrates to other parts of the pelvis and even the abdominal cavity - there are various options for ectopic pregnancy.

Ectopic pregnancy is one of the most dangerous conditions in gynecology, leading to serious consequences and even death of a woman. The first signs of ectopic pregnancy are:

  • Positive pregnancy test and menstruation delay,
  • Pain in the lower abdomen and back,
  • Spotting from the genital tract. Women, as a rule, describe this situation as follows: “I got pregnant and my periods went poorly and with a delay of about 1-2 weeks.”

That is why for any bleeding in the first month after conception it is necessary to exclude an ectopic pregnancy.


Even if the ovum fell into the uterus and implanted in the mucous membrane, variants of this attachment are possible. Normally, the egg must occupy a position at a certain height on the internal cervix of the cervix. The following options for the attachment of chorion and placenta:

  • Low adherence or placentation,
  • Regional attachment or placentation,
  • Central attachment or placenta previa, or chorionic.

The closer to the cervix the embryo is fixed, the more often the patient may have spotting during pregnancy. The fact that during the pregnancy the chorion and the placenta tend to “move” along the wall of the uterus is good news. So the options for low placentation turn into normal.

Sometimes women have some nuances in the structure and functioning of the genital organs, which can provoke the appearance of bleeding during pregnancy.

Two-horned uterus, doubling of the uterus, or a septum in the uterus, are variants of congenital uterine anomalies. Sometimes, on the background of such features, the patient has problems with pregnancy, and sometimes - a woman gives birth to several children and does not realize her “zest”.

However, it has been proven that women with uterine abnormalities often have uterine bleeding at times during pregnancy. In patients with a double uterus or a pronounced additional horn, "monthly" after conception are possible. In this case, the threat of abortion is absent, and blood is released from the second uterus or horn — this is called the decidual endometrial reaction.

Inflammatory diseases of the cervix, especially its structure, the presence of rough scars or polyps of the cervix can mimic the "monthly". Such bleeding most often occurs after sexual intercourse, examination by a gynecologist or taking smears.

As much as we would not want every pregnancy to occur easily and also proceed safely, but no one has canceled natural selection. Women complain that the "monthly" began after conception and go for several weeks. In this way, nature "cultivates" defective embryos in early pregnancy, preventing the birth of children with deformities.

That is why it is important to understand that persistent bleeding during pregnancy for no apparent reason (low attachment of the chorion, two-horned uterus, disorders of the blood coagulation system, etc.) may indicate the presence of genetic abnormalities in the fetus.

Хочется отметить, что в странах Европы и США беременным женщинам с кровянистыми выделениями никто не назначает никакой «сохраняющей» терапии, так популярной в наших странах. Scientists and doctors believe that nature should be given a chance to cope with its task of natural selection. It should be noted, their tactics are bearing fruit - artificial interruptions of pregnancy for genetic reasons in these countries are much less.

It should be understood that a pregnancy that has occurred with the help of assisted reproductive technologies (IVF, ICSI, insemination) is not very common in itself. The early periods of such pregnancies take place under the guise of various hormonal drugs and special treatment. Spotting against the background of such pregnancies "from the tube" can sometimes appear and require correction of maintenance therapy.

Summing up the results of our article, I would like to say that if a woman became pregnant and went on a period of pregnancy on the background of her pregnancy, it is necessary to consult a doctor and find out the reasons for such deviations.
