Implant bleeding - how to distinguish, timing


Most women believe that the delay in menstruation is the initial symptom of pregnancy. But at the earliest pores completely believe this indicator is not worth it. Delay often occurs due to climate change, illness, stress, overwork. There is one more indicator, due to which conception is determined in the early stages - implantational release of blood. This process is very similar to menstruation. It is easy to distinguish between implantable discharge and menstruation, if you know the main differences between these phenomena.

What is implant bleeding?

Such bleeding is an ordinary gynecological manifestation and can occur in any woman after sexual intercourse. Fertilized mature egg must pass through the fallopian tube to the body of the uterus with further attachment to its mucosa. The process of fixing the fruitful eggs in the cavity of the uterine wall in medicine is called implantation.

When an egg cell is introduced, the integrity of the uterine mucosa is impaired, and microdamages of blood vessels may occur. Such a process sometimes causes bleeding before a delay. Since the movement of the egg through the fallopian tube lasts 6-7 days, bleeding occurs about a week after intercourse.

Does implant bleeding always happen?

Doctors say that this manifestation is natural, but does not occur in all pregnant women and not always. Often the introduction of the embryo proceeds very calmly, and the amount of discharge is so minimal that it is almost imperceptible. Only twenty women in an interesting position, out of a hundred, are witnessing such a process. Often it coincides with the beginning of menstruation and just remains unnoticed.

How to define it and not to confuse with monthly?

For girls who constantly and closely monitor their female health and cycle, it is easy to distinguish menstruation from bleeding during implantation of the egg. To do this, you need to focus on such manifestations:

  • the time of occurrence of blood discharge,
  • their duration.

Menstrual phenomena are always more abundant and begin on the same day of the month, except in cases of unsystematic menstrual cycles. Many girls during critical days are worried about abdominal pain, feeling unwell. At the beginning of the menstrual cycle, bloating or indigestion sometimes occurs. During bleeding during implantation, these symptoms are absent. Spotting appears for a couple of hours, then stops and may resume briefly. They proceed very quickly, and many girls do not understand what happened.

Characteristic symptoms and signs

The main signs of implantation bleeding are called:

  • Intensity and duration. Such secretions are minimal and short-lived, it may be a few drops of blood or spotting that pass after a few days.
  • Highlight color. For all the time, their color varies from very light to darker, but differs significantly from the shade of blood during menstruation.
  • Pains On the day of the start of the discharge during implantation, a slight painful sensation is possible in the lower abdomen. This is due to spasms of the walls of the uterus during the introduction of a fruitful egg. With very severe pains a miscarriage often happens, so it is urgently necessary to consult a doctor.
  • Timing. Implantation begins after 5 - 10 days from the day of conception. Or 3-6 days before the start of critical days. However, most girls may not even know about their pregnancy and do not attach particular importance to this. Or they cannot figure out, this is implantational discharge or menstruation.
  • Effects. Basically, this phenomenon occurs without any symptoms, sometimes some women experience fatigue and weakness throughout the day.
  • Basal temperature. Lowering the basal temperature is so insignificant that for every other girl it is imperceptible. Its decrease is monitored only on day 1, after it rises again.

Pay attention to other circumstances that talk about implant discharge, and therefore, the onset of pregnancy:

  1. Nausea. Especially in the mornings or when trapping various odors (coffee, food, perfume).
  2. Soreness of the mammary glands. Chest pain may be a symptom of pregnancy. But such pain often warns of the imminent onset of menstruation.
  3. Fatigue. If you feel exhausted, despite the fact that you have not been subjected to any physical exertion, you may be pregnant.
  4. Regular use of the toilet. Frequent urination indicates possible pregnancy.
  5. Mood swings. Conception creates hormonal changes in the body, which are accompanied by changes in mood. Although this feature is typical for the early onset of menstruation.
  6. Dizziness. With a sharp rise from the place may dizzy.

What day does the cycle take and how long does it take?

As a rule, discharge occurs on the 21-25 day of the menstrual cycle or on the 7-9 day after ovulation, which ended with conception. However, in exceptional cases, implantation discharge occurs during menstruation. Then you need to pay attention to the amount and color of blood. The process of bleeding during implantation proceeds very quickly. In 70% of women, the period of such discharge lasts several hours, in the remaining 30% it can take a day or two.

The concept of implant bleeding

And in the middle of the menstrual cycle, ovulation occurs on days 12–16. The egg cell leaves the follicle to search for sperm. Upon successful collision of two components of one process - the egg cell and the sperm cell, fertilization occurs. About 9 days, the resulting zygote develops autonomously, increasing in size. In the interval from 5 to 7 days is carried out in the uterus. From the point of view of physiology, the process is not quite low-impact. The cage must "snatch" a certain portion of the uterine lining, to get to this place. That is, there is a destruction of the integrity of the tissues of the penis, blood vessels. Conditional implantation bleeding appears.

Characteristics of implantation bleeding

Since this is a process of microscopic level, a great loss of blood simply cannot be by definition. There are a few drops of blood that barely stain the normal discharge of a woman. The color may be pink, with red dots, brown. Droplets of blood, falling into the vagina, quickly collapse under the influence of the acidic environment of the penis, oxygen. Brown color appears.

It is possible to take implant bleeding for the beginning of menstruation, but this opinion disappears after 2 days. The implantation process takes from several minutes to 2 days. The amount of discharge is much less than at the beginning of menstruation, which tends to increase with each day. In addition, implantation bleeding is observed a week before the expected menstruation.

Often women ask themselves the question: “What does implantation bleeding look like?” Because, being already pregnant, they cannot remember their condition at the time of implantation. Quite a normal situation. Because most women simply do not notice this. This is evidence that the process for the female body as a whole is not traumatic, not painful. Blood excretions are insignificant or nonexistent.

Another variant of the frequently asked question: “On what day after conception does implantation bleeding occur?” As the brown, pink discharge between menstruation may be present for another reason. Experts have determined the period - 5-7 days after conception.

Sensations during cell implantation

Women love to share the impression of someone as it was. Some say they felt pregnant right after fertilization. Others - a week after ovulation. Third - after the delay of the proposed menstruation. Such a difference in the individual characteristics of the body - sensitivity, suspiciousness.

Experts say the process of inserting an egg into the uterus is so microscopic that it is completely unnoticeable for a woman. Symptoms such as aching pain in the lower abdomen are subjective. It is also physically impossible to feel conception directly after fertilization, before implantation of the egg. As the zygote develops autonomously. Communication with the mother's body yet.

With regard to sensations after implantation bleeding - slightly pronounced first signs of pregnancy. Mood swings, feelings of euphoria alternate with depressed state, laziness, drowsiness, indifference to former duties. That is, changes in psychological and emotional terms are mostly palpable. All other sensations - nausea, headache, etc., appear somewhat later.

Dangerous bleeding

Clear signs of bleeding during pregnancy are considered dangerous. Implant bleeding is present only 5–7 days after conception. On other days of the menstrual cycle, bleeding indicates the presence of pathological processes. The timing must be taken into account, since the sudden onset of menstruation a week before the expected date may indicate the beginning of the process of rejection of the attached cell. This is evidenced by menstruation during pregnancy, which began after a delay of 1-2 weeks.

Pregnancy is in jeopardy for 3 months. During this period, the body gets used to the new state. It can allow the further development of the egg and the course of pregnancy or to stop it. For one reason or another, there is a threat of miscarriage. It all begins with pain in the lower abdomen, minor discharge of blood, which then turn into bleeding. To prevent a situation, you must seek help immediately after the appearance of unusual discharge.

Sometimes implant bleeding is confused with secretions from an ectopic pregnancy. They can appear on any term, but turn into bleeding after a delay of periods about 2 weeks. Pregnancy initially proceeds as usual, but as the embryo grows, physical discomfort appears. This threatens not only abortion, but also internal bleeding for a woman.

Thus, it should be understood that:

  • implantation bleeding begins only as a result of conception,

  • occurs on day 5–7 after conception,
  • indicates the beginning of pregnancy
  • until the expected menstruation remains 1 week,
  • the amount of discharge is minimal, it may not be visible at all,
  • this does not cause any painful sensations.

All other situations that go beyond this are not implant bleeding.

Is it possible to do a pregnancy test at the end of implantation

Women are always in a hurry to learn about pregnancy. Whether desired or not. The long-awaited pregnancy is a reason for joy, an unplanned makes you seriously think what to do next - an abortion or childbirth? A pregnancy test is an affordable tool that allows you to determine if you have a pregnancy at home for 1 minute. Especially sensitive pregnancy tests allow you to do this from the first day of menstruation. To the term of the alleged menstruation to analyze is meaningless. Results will be false even if 2 bars appear. Why?

With the onset of pregnancy, hormonal balance, blood composition changes. Starts to increase hCG. The hormone is increasing every day. But in the early stages of pregnancy, it remains invisible to the methods of analysis. In addition, in the urine the level of hCG increases more slowly. A significant amount of it is present 1 week after the delay of menstruation. To determine the conception from 1 day delay using the most sensitive tests. But it is recommended to repeat the analysis after a few days.

Implant bleeding is the beginning of pregnancy. Up to this point there are no signs of conception. If blood excretion continues for more than 2 days, you should seek the help of specialists. Menstruation 1 week before the expected date begins only under the influence of adverse factors, the presence of disease.

When implantation bleeding occurs

Implantation bleeding signs (symptoms) is slightly pronounced, and each of them individually looks like menstrual on the days when it begins to "grease". To determine for yourself on which day implantation bleeding appears, then, based on elementary calculations, it can be assumed that this will occur 5-6 days before the expected menstruation.

Therefore, it will be possible to find out exactly what happened - implantation bleeding or menstruation in a week: if there is a delay - we are talking about pregnancy, if the menstruation has come in time - it means there was no conception.


So, if the bleeding begins about a few days before the planned monthly and lasts a maximum of two days - this is implant bleeding, which can be a sign of pregnancy. Menstrual bleeding continues on average from 4 to 7 days.

The way implant bleeding looks like is one of its significant differences from other bleeding, including menstruation.

  • Very scanty in the amount of blood secreted: you can find a few drops of blood on the laundry. Sometimes it looks like small streaks of blood on linen. So you can call it bleeding with a stretch.
  • Implant bleeding with the release of a large amount of blood is extremely rare and is already interpreted as a pathological process associated with some existing disease of the organs of the genital sphere, when other signs have not yet appeared.

If the discharge in bleeding contains blotches in the form of mucus, lumps and other things - these are signs of the onset of menstruation, but not implantation bleeding.

Another distinctive symptom is the saturation of the color of bloody discharge. Usually the blood is light-colored, unlike dark menstrual. In combination with the early onset of menstruation and a small amount of discharge, these are the exact symptoms of implant bleeding.

The list of distinctive features must necessarily include pain, which accompanies menstruation and is almost absent in case of implant bleeding. Only occasionally, bleeding after conception can be accompanied by signs of weakness, drawing pains or cramps that do not cause much discomfort. But they do not last long.

Changes in basal temperature as a sign of implantation

Basal temperature, if a woman carefully monitors her condition and constantly measures it, is an exact symptom by which you can exclude menstruation. But it is quite difficult to track it: a decrease in temperature during the implantation of an egg is very short. This occurs on the day of implantation, after ovulation, from about 6 to 10 days.

Then the numbers of the temperature curve become the same. If the basal temperature is monitored regularly, then against the background of an elevated temperature, any slight decrease after ovulation is very noticeable.

The duration and timing of implant bleeding

Deadlines — on which day after conception implantation bleeding occurred — are easily calculated by comparing the dates of the last sexual contact and the appearance of discharge. Usually bleeding begins a week before the next menstruation. When asked how long the implant bleeding lasts, there is no exact answer, because it is an individual response of the body.

If the bleeding that has occurred continues for more than two days, this is a reason for hospitalization, since there is a high probability of hormonal disruption, miscarriage in the early period or other reasons that need to be sorted out. All other clinical signs of doctors consider the norm.

About 30% of pregnant women came across this and observed something similar. How many days implantation bleeding lasts - from the statistical responses of women who observed it, it turned out: from one hour to two days. Longer this phenomenon cannot occur physiologically, since during the implantation of the egg into the wall of the endometrium, only a small damage to the capillary network occurs.

Accuracy of early pregnancy diagnosis

Since this phenomenon is initially regarded as an early sign of pregnancy, many people have a question: did the implant bleed happen and when should a pregnancy test be performed. This makes no sense: in such a short time this method will not help determine the condition of a woman. Even the cherished two strips will not become the guarantor of the "interesting" position.

Тест нужно проводить, когда пройдёт время предполагаемых месячных, то есть когда появились признаки успешной имплантации в виде наступившей задержки. And for greater accuracy, the test will need to be carried out repeatedly, using indicators from different manufacturers, to finally dispel doubts.

There is a more reliable way to determine how successfully the implantation of a fertilized egg has occurred - to find out the level of human chorionic gonadotropin (hCG). It increases almost immediately after implantation.

At the initial stages of pregnancy, the shell of a fertilized egg constantly releases hCG, and its level rises with time, which is necessary for the normal course of pregnancy. A positive result can be observed already at the time of implantation of the egg into the epithelium of the uterus. But in order to make the analysis more convincing, it is better to perform the analysis some time after the implantation bleeding.

Early diagnosis for a woman who wants to keep a pregnancy is very important. In the case of a positive result, there is time to take up the state of one’s health, to register with a gynecologist as early as possible and not to disturb a healthy lifestyle, perhaps to give up some bad habits. This is especially true for women who have long been unable to get pregnant for some reason.

Despite the scarcity of secretions, it is necessary to carefully consider any changes in the body, since a small amount of blood, even in the form of veins, can be not only a natural physiological process, but also be accompanied by serious diseases.

These include:

  • cervical erosion,
  • some sexually transmitted diseases
  • tubal inflammation
  • neoplasms of female genital organs,
  • bacterial vaginitis.

Therefore, in order to preserve your health, it is necessary to consult a doctor in any doubtful cases in order to find out the cause of the bleeding and to exclude dangerous diseases.

How long does implantation bleeding last?

Normally, bleeding is observed. on day 6-12 after unprotected intercourse - it takes so much time for the egg to reach the uterus and attach to it. It turns out that they are long before the planned arrival of menstruation.

The day of implantation is easy to calculate. With a standard cycle of 28-30 days, ovulation occurs on day 14. If conception has occurred, implantation bleeding will begin no later than 10 days from the onset of ovulation and approximately 7 days before the expected period of menstruation.

The spotting may stop for a while and then continue again. But their duration never exceed two days.

Often this bleeding lasts only for two hours.

They come in the form of:

  • The blood streaks in mucus secreted from the genitals.
  • Small droplets of blood.
  • Sediment pinkish, brownish or creamy.

No clots should be!

Implant bleeding is such discharge, which is often difficult to determine, and only a gynecologist at the reception notice them.

Signs and symptoms

In order not to confuse these bleeding with menstrual or pathological, it is important to know their main signs and symptoms:

  • Pulling and pressing pains in the lower abdomen. They look more like discomfort and discomfort, not strong. Caused by muscle spasms during the implantation of an egg into the uterus.
  • Decrease in basal temperature. Slight and barely noticeable. Literally for 1 day.
  • Weakness, lethargy, constant feeling of tiredness and drowsiness.
  • Dizziness.

The specifics of the norm

First of all, you need to understand what is this phenomenon. It is difficult to call bleeding moderate, sometimes clot-like discharge pinkish, less often brown.

Does implant bleeding always happen? This phenomenon occurs in 20-30% of cases and causes panic in those who want to become parents, because the appearance of blood characterizes a failed pregnancy. However, depending on which day after ovulation the discharge appears, you can, on the contrary, confirm the conception of a new life.

The reason for the wrong time (and sometimes in time) discharge is quite natural. The fact is that the egg, trying to attach to the wall of the uterus, injures the vascular wall of the villous epithelium or the mucous membrane of the cervix, thereby causing bloody discharge.

This is not monthly!

It is known that those who had implantation bleeding often took it for the beginning of menstruation and therefore did not attach any importance to it.

Additional signs of pregnancy, and subsequently its incorrect duration, became a surprise.

In order to distinguish the rate of embryonic attachment from the onset of menstruation or the appearance of the disease, you should know how long does it take implant bleeding and on what day of the cycle it occurs.

If the menstrual cycle is regular, the blood often appears on the 20-26th day of the cycle, which is equivalent to a period of about a week or several days before menstruation or after 6-11 days after ovulation and subsequent fertilization.

However, the fixation of the egg individually and can occur at completely different time after ovulation:

  • average, 7-10 days,
  • early, 6-7 days,
  • later, more than 10 days later.
Experts call the most common term from 7 to 10 days.

Late fixing occurs in 98% of cases with IVF.

It is important to know how many days implantation bleeding can last normally. The discharge lasts no more than 1 day, usually several hours. Rarely traces of blood remain on the strip for more than 2 or 3 days. However, since the organism is individual and a woman may additionally have chronic diseases, these periods are conditional.

An important criterion in determining the implant bleeding or menstruation is the intensity and color of the discharge - when the embryo attaches, the blood volume does not increase, as is the case with menstruation.

it almost always smearing light traces, sometimes - beige stained spots. Some women who had implant bleeding noticed only one bloody speck.

There is no unpleasant odor or severe pain, as is the case with venereal disease or other problems.

Additional symptoms

It is important to understand that in the absence of ovulation, if a woman has such problems, fertilization and, accordingly, embryo implantation it can not be. Also, if sexual intercourse was more than a month ago, the blood that appeared on the gasket cannot be a sign of an imminent pregnancy.

Signs of implant bleeding are implicit in 80% of cases. The most accurate symptom of the beginning process of egg attachment is the change in basal temperature on the 1st day of the cycle, usually it is lower by 1-2 degrees.

You may notice further symptoms:

  • moderate, not increasing pain in the lower abdomen,
  • heaviness, bloating in the stomach,
  • dizziness, sometimes headaches,
  • weakness.
These signs will soon pass away, and, in the event of pregnancy, others may come.

If a woman or the people around her begin to notice drastic changes in her mood and excessive weakness, we can assume beforehand what had happened. Symptoms will be more pronounced:

  • nausea,
  • frequent urination,
  • swelling and tenderness of the mammary glands.
However, in some cases, these symptoms may indicate a disease.

When highlighting is not the norm?

In the event that the probable signs of conception appeared 2-3 weeks after the intended conception, this is a signal to the body about the problem.

First of all, the gynecologist may suspect a molar pregnancyin which the fetus is recognized as non-viable. The reason is the lack of chromosomes from both parents.

Lack of progesterone, which can also be assumed due to the start of blood excretion, will lead to miscarriage or missed abortion.

Also, spotting is easily confused with placental abruption or its insufficient function.

In addition, we can talk about such problems:

  • damage during intercourse,
  • STDs
  • candidiasis,
  • endometriosis,
  • vaginosis
  • hormonal imbalance
  • inflammatory processes in the problem area,
  • miscarriage.
Ectopic pregnancy can also cause abundant or moderate bleeding, but more often it is accompanied by sharp pain.

How to diagnose?

Confirmation / Denial of Pregnancy begins with a survey of women and examining her on the gynecological chair. The doctor will take a scraping on cytology.

First of all, to exclude diseases, the gynecologist will prescribe general blood and urine tests. Also, to determine the possible pregnancy, use a blood test for hCG.

Additionally, it is necessary to determine the balance of hormones. On ultrasound, you can see not only the presence of pregnancy, but also its estimated period, or neoplasm, which caused the bleeding.

Is treatment necessary?

Discharges indicating attachment of the egg, considered normal for the female body and do not require any medical intervention. Therapy is needed if the gynecologist suspects from the results of a study of the pathology of the fetus or the expectant mother. Also, with the exception of conception or abnormal discharge, the woman should be recommended the necessary treatment.

Frequently asked Questions

When to do a pregnancy test after implant bleeding? After how many days the test will show the result? - Experts advise to conduct the test on the 10th day after ovulation or on the 7-10th day after the cessation of secretions. A blood test for hCG can be performed earlier - 1-3 days after discharge.

Is there always implant bleeding during pregnancy?? - No, this phenomenon occurs only in 30% of cases.

Can Implant Bleeding Be Abundant? - No, the selection is always scanty. A large amount of blood, however, is possible, but with concomitant problems.

Can implantation bleeding occur after a delay and on the day of menstruation or during ectopic pregnancy?? - Yes, the discharge can begin both before and during and after menstruation. Isolation of blood that begins after the embryo is attached outside the uterus (ectopic pregnancy) cannot be called implantation.

Bleeding, which is called implant bleeding, is rare, but not considered a deviation from the norm.

It is important to differentiate it in time from menstruation and serious pathologies.

Therefore, it is best not to engage in self-treatment, and immediately after the cessation of discharge, consult a gynecologist for advice.
