What discharge occurs during implantation of the fetal egg. Embryo implantation - is it possible to feel the beginning of a long-awaited pregnancy

The introduction itself is possible only on certain days of the cycle, this is due to the process of ovulation. All these data must be taken into account when planning. artificial insemination. It is not yet possible to see the embryo, but after passing the analysis for growth hCG hormone, you will be able to accurately determine whether you are pregnant or not. And after 1-2 weeks, the test will show the long-awaited for many two strips. It is important to note that there are no obvious symptoms of attachment of the fetal egg to the uterus. Although some women experience tingling in their lower abdomen, aching pain, back pain, weakness, heaviness in the uterus, etc. All this can be considered individual manifestations, but by no means the rule. It is almost impossible to feel it, from the point of view of medicine, this is not confirmed in any way. Since the process occurs at a microscopic level and is not accompanied by intense manifestations on the part of the woman's body. Enough a rare symptom attachment of the fetal egg to the uterus are small discharges, which often cause concern for doctors, as they may also indicate other diseases and require a thorough examination by a specialist.

This difficult process most often occurs on days 18-22 menstrual cycle. Many expectant mothers may not even be aware of the onset of pregnancy. Usually during this period a woman feels well, there are no manifestations early toxicosis or the whole process is almost asymptomatic. If the attachment itself did not occur or it did not take root due to many circumstances, menstruation occurs and no one can even assume an undeveloped pregnancy. If the implantation was successful, then the fetal egg is tightly attached to the endometrium and the active phase of fetal development begins. After that, menstruation, as a rule, does not occur.

Discharge during attachment of the fetal egg

It is considered normal to have a small discharge when the fetal egg is attached to the uterus. This does not occur in all women and is more an exception to the rule than an accurate sign. long-awaited pregnancy. Special attention you need to pay attention to the volume and color of the discharge. If this is really a discharge associated with the implantation process, then their amount should be no more than a few drops during one day, without any blood clots. The color of the discharge can be red, light yellow, brown or pink. Most often, discharge occurs 7-8 days after the sperm enters the uterus. But this data is quite subjective and depends on individual characteristics every woman.

If you notice that the discharge has become larger and they are red, you should immediately consult a doctor. These could be signs of a threatened miscarriage or uterine bleeding. In this case, every minute will be important, because the life of your baby and yourself will depend on it. In addition, such discharge may be the first signs of more serious illnesses, which include oncological diseases, hormonal disruptions, benign tumors, exfoliation or inflammation of the endometrium, erosion, cervicitis, etc. Only a specialist after a thorough examination will be able to deliver accurate diagnosis and appoint proper treatment. Therefore, do not forget to visit a doctor regularly and take appropriate tests.

What affects the success of implantation

When planning a pregnancy, it is important to consider some factors that will stand in the way of your goal. The fetal egg at the time of attachment is quite sensitive to external environment and needs special conditions for further development. If you have had medical abortions, miscarriages, pelvic inflammatory disease, you need to undergo thorough treatment with a subsequent examination that will confirm the readiness of the uterus and in particular the endometrium, to future pregnancy. Since if a fragile embryo enters the inflamed uterine cavity, it will not be able to survive, and its further development will be impossible. You should also be tested for the level of adrenal hormones, progesterone, estrogen, etc. These hormones play a crucial role in the conception and development of the fetus.

Even when planning a pregnancy, you should consider the duration of admission. hormonal drugs and duration of use intrauterine device. All these factors make the internal lining of the uterus not sensitive enough, as a result of which placentation or cervical pregnancy may develop. Don't forget also about bad habits. Refrain from drinking alcohol and smoking. Try to spend more time fresh air give preference to food low-fat varieties meat and fish, fresh vegetables and fruits that are rich in vitamins and minerals natural origin. Avoid contact with harmful substances and if you are taking any medications, talk to your doctor about side effects.

Attachment of the fetal egg to the uterine cavity is one of the most important stages in the development of the embryo. The further development or underdevelopment of pregnancy depends on how this process will take place. Therefore, it is important to listen to the advice of a gynecologist and then in 9 months you will have a healthy and strong baby.

Implantation of the fetal egg is the very beginning of the pregnancy period. It's almost imperceptible future mother but nonetheless incredibly important for a child's development. Its importance is confirmed by the fact that if the fetal egg is not implanted, the child simply will not work.

In this article, we will look at the symptoms of implantation of the ovum, its timing and the sensations that a woman may experience. Many scientists claim that for the first time a woman feels something after implantation, however, the discharge during implantation of the fetal egg can say a lot.

When does implantation of the fetal egg occur: timing

Implantation of the ovum - the day on which the egg is attached in the uterus. This usually happens four days after successful sex. The attachment period itself takes about 48 hours.

It is at this time that the body begins to produce the hCG hormone. Thus, after a week and a half, you can take a test and find out about a possible pregnancy. And you don’t have to wait for the mythical signs of implantation of the fetal egg.

However, it must be remembered that best result will give a blood test, which can be taken in any paid clinical office.

Symptoms of implantation of the ovum

Yes, many doctors claim that pain during implantation of the fetal egg is simply impossible and cannot disturb any of the women, since all this happens at the cell level and the size of the fetal egg is minimal. However, many women claim to have felt pulling sensations in the lower abdomen, and their nature is completely incomprehensible.

As for the discharge during implantation of the fetal egg, then this is a completely different matter. It can be meager (and only such) discharge with small impurities of blood. Otherwise, the reason for the appearance of such symptoms can be alarming. So, bleeding and other discharge in the middle of the menstrual cycle may not indicate the implantation of the fetal egg, but a deterioration physical condition women.

So, if we talk about the sensations during the implantation of the fetal egg, then it can be argued that this moment passes without a trace for most women. At the same time, it is worth remembering that the implantation of the fetal egg, the signs of which are too obvious for a woman, most likely indicates that she was unsuccessful, and it is worth seeing a doctor.

Overview of the process of implantation of the ovum

So, what a woman feels, what kind of discharge during implantation of a fetal egg she can have, is described. Now we can move on to the "view from the inside." Namely, to consider how the egg cell behaves at this time.

The egg begins to move towards the uterus. At this time, she still continues to share. Doctors during this period no longer call it an egg, but a morula. At this point, it consists of thirty-two cells and outwardly resembles a raspberry.

For three days, the egg moved into the uterus, and then for the same amount of time it continues to move to the place of attachment. By the time of the sixth day, the morula becomes a blastocyst. At this moment, there are two hundred and fifty cells in it and its dimensions are already one and a half millimeters. It already consists of two layers - a fleecy surface (trophoblast) and the embryo itself (embryoblast). The temperature during implantation of the fetal egg should not exceed the norm. Therefore, if a woman plans to become a mother, she is not recommended to take very hot baths. The villi help the fetus to merge with the mother's body. And the whole process takes at least forty hours.

For the first time, you can consider the future baby three to four weeks after the implantation of the fetal egg. At this time, it reaches a size of about a centimeter.

Much of a woman's knowledge of how pregnancy begins ends at the stage of ovulation and fertilization. Actually, the success or failure of the planning cycle is attributed to the fateful "meeting" of male and female germ cells. However, in the development of a new life in the body of a woman, there is another complex and important point - embryo implantation. In order to increase the personal literacy of planning ladies, this issue should be given special attention.

A bit of theory

Implementation fertilized egg into the uterus called implantation. The villi of the embryo penetrate the lining of the uterus, which can cause minor bleeding.

In order for implantation to be successful, several conditions must be met at once:

• lush three-layered endometrium with great content substances that feed the embryo;
• high amount of progesterone in the body (so that the embryo can develop and menstruation does not begin);
• normal microflora in the body.

The process of fertilization and development of the fetal egg- not one-time. And each stage has importance for the offensive normal pregnancy and development of a healthy fetus.

Timing of implantation

After ovulation and the meeting of the egg with the sperm, the fertilized zygote begins to move through the fallopian tubes. Her task is to get into the uterus as quickly as possible in order to gain a foothold in the endometrium specially prepared for this. On the way, the zygote continuously divides and grows. In stage blastocyte implantation and happens.

It is conditionally possible to distinguish middle, late and early implantation.

• Early. It occurs quite rarely. Usually, implantation is considered early if it occurs 6-7 days after ovulation (or 3dpo - 4dpo If we are talking about IVF)
• Average. 7-10 days pass between fertilization and implantation ( embryo implantation after transfer comes around 4-5 days). Doctors say that the introduction of morula takes about 40 hours, after which the body begins to produce the hormone hCG in the blood, it rises basal body temperature. Based on this, the so-called. the embryonic period of development, which lasts until about 8 weeks of gestation.
• Late. It occurs approximately 10 days after fertilization. This is what always gives women even a weak, but hope for possible pregnancy- even when you can't wait.

If pregnancy does not occur long time, then you need to be examined to identify the cause of infertility.

Subjective and objective signs

Both in the natural and in the artificial cycle, women are very excited and want to quickly open the veil of secrecy - is there a pregnancy or not? They start collecting symptoms and sensations, trying to find in their well-being some kind of relationship with reality. Experts took as a basis a simple classification, according to which all signs can be divided into subjective and objective.

Subjective:

• pulls the stomach;
• discharge;
• mood changes, emotional lability;
• tingling in the uterus after ovulation;
• feeling tired, etc.

Girls may even point out that after IVF, the stomach hurts like before menstruation. In this case, while there is no clear certainty, such pain may indicate both the onset of pregnancy due to successful implantation, and the approaching end of the cycle - and the beginning of a new one.

Objective:

• the basal temperature rises after the transfer (after a slight retraction in the natural cycle);
• body temperature after transfer can also increase from 37 to 37.9 degrees;
• detection of hCG hormone in urine and blood.

In this case, it is necessary to distinguish between the levels of pain, the abundance and saturation of secretions, an increase in body temperature. Sometimes what passes for implantation of the ovum signs are symptoms of some other disease. If you are in doubt whether your feeling 5 dpo signs fetal implantation or not, it is better to consult a doctor.

Embryo development by days after IVF

If with natural cycle everything is more or less clear, the question is, on what day does the implantation of the embryo occur in a successful protocol remains open. We bring to your attention a table by day:

0 DPP - transfer ( cryotransfer)

1DPP- the blastocyte comes out of the shell

2DPP- attachment of blastocytes to the wall of the uterus

3DPP- implantation begins

4DPP- Implantation of the morula into the uterus continues

5DPP- end of implantation

6DPP- the placenta begins to produce hCG

7DPP - active growth hCG levels

8DPP- HCG continues to rise

9DPP-10 DPP - hCG level reaches the minimum of pregnancy tests

About Day 11 ( 11-12 DPP) after the transfer, it is possible to draw conclusions about whether it was successful IVF.

We trust nature

Women re-read tons of literature, trying to find the very ones 5 dpo feeling or 6 dpo sensations, which would indicate implantation and, accordingly, the onset of pregnancy. Actually, to worry about whether it worked out or not, expectant mothers begin to 3 DPO.

This question equally excites girls who have undergone IVF. supposed embryo implantation after IVF They try to catch by minimal changes in the body and well-being. The Internet is full of requests, like " 5 dpo three days», « 4 dpp five days ", « 7 dpo five days with which women look for positive stories.

A bitter disappointment is the absence of even a hint of a second strip on Day 8 or period after embryo transfer. But in fact, the answer to the question of whether why the embryo does not take root, may be an objective situation of natural selection. The unviable fetus was rejected, giving way to healthy offspring.

In fairness, it should be noted that if such rejection is repeated constantly, then this is an occasion for a full medical examination. The reason for the failure of a long-awaited pregnancy may be male infertility.

Implantation is a critical point, because a blastocyte is perceived by a woman's body as a foreign object, due to the presence of male genes in the cell. The speedy and successful introduction into the endometrium and the onset of a normal healthy pregnancy depend on how well the defense mechanisms of this cell work.

For the onset of pregnancy, one conception is not enough, it is also necessary for the fertilized egg to be able to gain a foothold in the uterine cavity and begin to develop. This process is called implantation. In this article, we will tell you how implantation takes place, when it happens, why the egg cannot be implanted, by what signs a woman can guess about implantation.

What it is

After the female egg meets the sperm cell, an intensive process of transformation of the oocyte into a zygote begins. After the fusion of 23 female and the same number of male sex chromosomes, a full-fledged zygote cell is obtained, which contains 23 chromosomes - all information about the future baby, including his gender, height, hair color, eyes, possible talents and hereditary diseases. The zygote is constantly crushed and sent towards the uterus.

From the fallopian tube, where the fertilization process takes place, to the uterus, she has to move for several days. All this time, the fertilized egg grows, gradually turning into a blastocyst. On the 7-8th day after ovulation, the embryo enters the uterus, where its fate must be decided. If the implantation of the embryo into the wall of the uterus occurs, pregnancy will occur. If this does not happen, the woman will have her next period almost on time, and she may never know that she was just one step away from pregnancy.

After conception, the zygote forms two shells - external and internal. It is the outer one - the trophoblast - that is responsible for attaching the fetal egg. The implantation period lasts up to 40 hours during natural pregnancy and up to several days with IVF. That is how long it takes for a complex process consisting of two stages to be completed completely.

The first stage is adhesion. The fetus is attached to the wall of the uterus, sticks to it. The second stage is invasion. At this stage, the trophoblast cells are transformed into thin villi, which begin to penetrate into the endometrium of the uterus, "burrow" into it. The villi produce special enzymes that dissolve endometrial cells. It turns out a “cozy nest”, into which the fetal egg deepens. Now that it is firmly fixed, the trophoblast villi continue to move deep into the tissues of the uterus. It is they who form the chorion - the prototype of the placenta, it is on them from this moment that the responsible task lies - the nutrition of the embryo useful substances and oxygen from the mother's blood.

Implantation in a particular woman may be late or early. Early is called the attachment of the fetal egg within a week after ovulation. If this fateful process is delayed and occurs only after 10 days from the moment of ovulation, then implantation is called late.

Both those and other terms are an absolute norm. But still, there are certain prerequisites for late implantation. So, some pathologies of the fallopian tubes - for example, narrowing of their lumen - can "delay" the zygote on the way for 2-3 days. Embryos with abnormalities also descend into the uterus late cell division. But it is not late implantation that is dangerous, but early.

If the fetal egg descended into the uterus before the endometrium becomes sufficiently loose under the action of hormones, then implantation may not occur or pregnancy will occur, but will be accompanied by risks of interruption, fetoplacental insufficiency in the future.

Due to the action of progesterone after ovulation, the so-called pinopodiums on the endometrium are formed in the body of a woman - cellular "protrusions" that greatly facilitate the task of implantation. It takes time to form them; if the fetal egg sticks to the wall of the uterus earlier, then again, implantation may not occur and the embryo will die. If the implantation is late, then there is a risk that the pinopodes will already “dissolve” and then attachment may again fail. There are special structures of the endometrium for only 24-48 hours.

After the embryo is attached, if everything went well, production begins chorionic gonadotropin- the very hormone hCG, which is so important for diagnosing pregnancy. But it can be detected only after about a week, since its concentration increases gradually.

Peculiarities

Implantation is a rather individual process, in which much depends on the age of the woman, the state of her endometrium, hormonal levels and general condition health. There are some peculiarities when attaching the embryo after natural conception and in the cycle in vitro fertilization. Let's talk about this in more detail.

After natural conception

A woman cannot influence the processes after natural conception. She does not even know if the conception took place on the day of ovulation. The hormonal background also remains a mystery, but almost none of the fertile and healthy women does not think. Implantation after natural conception takes less time: both during the first and during the third or fourth pregnancy, it will proceed approximately the same.

The more pregnancies and childbirth a woman has, the thinner functional layer its endometrium, and therefore the low attachment of the fetal egg is not excluded, which can then lead to placenta previa. This can be diagnosed only at a period of 12-14 weeks of pregnancy.

In the IVF treatment cycle

Fertilization during IVF does not occur in fallopian tube, and in a test tube under the strict control of an embryologist. The eggs, the growth and maturation of which is stimulated by hormonal preparations, are taken by puncture and fertilized with a nutrient medium with the sperm of a husband or a donor. For several days, doctors monitor how many eggs are fertilized, evaluate their quality. And then they set the date for the transfer of the embryos into the uterine cavity.

Three-day or five-day embryos enter the uterus through a thin catheter inserted by a doctor into cervical canal cervix. But there is no need to wait for a speedy implantation. For several days they can swim freely in the uterine cavity, since they take food at this stage from the environment.

Implantation after in vitro fertilization lasts not 40 hours, but longer. Usually, the probability of attachment is discussed only starting from 3-4 days after the transfer of the embryos to the uterus. After cryotransfer, the process may take even longer. Embryos in the cryoprotocol and three-day embryos are implanted longer. In 5-day-old embryos, adaptive abilities are higher. They can begin to attach to the wall of the uterus within a few hours after the transfer. The probability of successful attachment of three-day-old embryos is estimated at about 40%, and the probability of implantation of five-day-old embryos is about 50%. Two-day or six-day embryos take root much worse.

The implantation process itself takes place similarly to natural conception. In the IVF cycle, the thickness of the endometrium is very important. If it is less than 7 mm or more than 14 mm, then the chances of successful implantation, alas, are low. The required thickness is “increased” artificially using hormonal drugs and is necessarily controlled using ultrasound diagnostics.

Signs and symptoms

If you ask a doctor the question of whether it is possible to feel the moment of implantation of the embryo, he is unlikely to be able to answer at least something intelligible with confidence. Official medical sources do not describe any reliable sign of implantation. But many women are sure of the opposite and claim that they quite clearly felt changes in their condition and well-being. From the point of view of medicine, this is possible, because already at the stage of invasion (immersion of the fetal egg into the endometrium) in the body of the fair sex, hormonal changes, and it is their consequences that a woman can theoretically feel.

Theoretically, this means that not every lady will notice unusual sensations, a lot depends on individual sensitivity. In the second or third pregnancy, the chances of feeling at least something are higher than in the first, when a woman simply does not identify minor changes in her state of health with pregnancy due to the lack of relevant experience.

So, what sensations can be accompanied by implantation:

• minor discomfort in the lower abdomen (the abdomen can “pull”, as before menstruation, but a little weaker);
• body temperature rises to subfebrile values ​​(37.0-37.5 degrees);
• a feeling of slight nausea, headaches, severe weakness, chills (while women in most cases sincerely believe that they have caught a cold);
• increased drowsiness, fatigue, slight irritability, anxiety;
• the appearance of a peculiar taste in the mouth, which women compare with the taste of a metal coin.

Especially it is necessary to dwell on such a sign as the appearance of a slight bleeding from the genital tract. This is the so-called implantation bleeding. We already know that invasion of the fetal egg is associated with the destruction of endometrial cells. The integrity of small vessels - capillaries is violated, the released blood must necessarily leave female body. And most often she does it naturally - through the vagina.

Implantation discharge sometimes confuses a woman, because there is still about a week before the expected date of menstruation. But many take them calmly and believe that menstruation has just begun. ahead of time according to the most various reasons(stress, quarrel, illness, fatigue, etc.). But this is not monthly. Bleeding stops within a day - a maximum of two. And no more unusual discharge is observed.

Implantation bleeding is not dangerous for either the mother or the fetus, it does not affect the subsequent course of pregnancy. It is not observed in everyone, which is also completely normal. The mechanism of its appearance or absence is not fully understood.

The basal temperature after the implantation takes place rises and keeps for quite high level. This is due to the increased concentration of progesterone, which ensures the development of pregnancy. Usually, the temperature after the attachment of the embryo is set at 37.0-37.5 degrees. A higher basal temperature is a sign of inflammation rather than pregnancy. Low temperature indicates low levels of progesterone. Even if the implantation was successful, the pregnancy can be terminated at any time precisely because of this hormonal factor.

During pregnancy, a woman can feel special sensations in her chest only a few days after implantation, when the level of chorionic gonadotropin becomes high enough.

The cervix after implantation may slightly change its color - from pink to cyanotic, due to increased blood supply to the female reproductive organ.

A gynecologist can determine some softening of the cervix in a week, cervical mucus under the influence of progesterone, it becomes thick and forms the very mucous plug, the discharge of which will be a signal of the onset of labor.

Why is attachment not happening?

Women who have been planning a pregnancy for a long time and so far unsuccessfully should definitely visit a doctor to find out at what stage there is a problem - conception does not occur or implantation does not occur. Very often, the problem of infertility lies precisely in the absence of the possibility for the fetal egg to implant and gain a foothold on the wall of the uterus.

Unsuccessful implantation may be due to:

• hormonal disorders (insufficient levels of female sex hormones, due to which there is no maturation and growth of the endometrium to the desired 7-14 mm);
• violations immune status women (when her own immunity perceives the fetus as a foreign object and seeks to destroy it);
• non-viability of the embryo (spontaneous genetic errors occurred during conception, fertilization occurred with two spermatozoa at once, the egg contained an inferior set of chromosomes, development slowed down);
• pathologies of the endometrium (thinning of the functional layer after several abortions, surgical curettage, inflammatory process such as endometriosis)
• tumors in the uterine cavity (endometrium with any tumor process deformed, which may interfere with the attachment and development of the embryo).

Amazing things can happen every day - next to us, around and even within us. And the most miraculous event, of course, can be considered the birth of a new life. From a tiny cell, a full-fledged and viable organism will have to develop, which will grow and become the successor of the family itself. But, despite the fact that two people are involved in the process of conception, only a woman can be the bearer of a new life. Therefore, our article is focused more on the fair sex. Only you can indirect evidence to guess that a great miracle is happening now, namely the attachment of the embryo to the uterus. On what day it happens, what signs it is accompanied by - we will talk about this now.

fertilization process

We will not dwell on this process in detail, we will only briefly go over to restore the entire logical chain. So, on a certain day of the cycle, the egg begins its journey through the fallopian tubes to the uterus. She will reach it anyway. Left unfertilized, here it will collapse, and there will be another menstruation. In this case, the endometrial layer that lines the uterus is also subject to rejection. But with the beginning of the next cycle, everything will start anew. The nutritive layer of the endometrium in the uterus will be restored, a new egg will mature, and under successful circumstances, pregnancy may occur.
For this, only one thing is now needed: the presence of viable spermatozoa that will get to fallopian tubes and fertilize the egg.

First trip

Now, no longer an egg, but an embryo begins its journey to a place where it can develop over the next nine months. The journey takes seven to ten days, counting from ovulation. Soon enough, the embryo will attach to the uterus. On what day this will happen, it is unlikely that it will be possible to unambiguously answer. It all depends on the cycle of the woman and the day on which the sexual intercourse took place. In addition, Y-chromosome-carrying spermatozoa are more mobile and can reach their goal faster, while its X-chromosome-carrying counterparts (future girls) are slower, but can live longer and wait for the egg to be released.

Short description

Now let's talk about what, in fact, is the attachment of the embryo to the uterus. On what day this will happen - you can find out exactly by scheduling ovulation. We will talk about this later, but a little later. So, the fertilized egg descends into the uterus and chooses a place for the final fixation. On this day, she sheds her zona pellucida to attach herself to the endometrium. It is called "trophoblast".

The expectant mother may not yet know what is happening in her body. And at this time, the villi sink deeper into the mucous membrane and secrete special enzymes. They contribute to the growth of the mucosa, which allows the embryo to burrow deeper. Here he will receive everything he needs for development: protection, nutrition and oxygen.

Protection Mechanisms

The mother's body is trying to diagnose the attachment of the embryo to the uterus. On which day this happens, we will soon find out. If not found genetic pathologies(from among those that the body is able to recognize), then the pregnancy continues. Otherwise, it starts normal menstruation. This process is completely painless, the woman does not even suspect what happened in her body.

Conditions for successful implantation

In order for the embryo to attach to the wall of the uterus, the important conditions. First of all, the endometrial layer in the uterus must have a certain thickness. The implantation is supported by a corpus luteum hormone called progesterone. Its main task is to stimulate the growth of the endometrium. In some cases, the shiny protective shell may be too thick. This can create barriers to successful "implementation".

Types of implantation

In official science, implantation is classified into early and late. Both types are divided depending on when the implantation of the embryo occurs. What day does this happen? Early implantation occurs on the sixth or seventh day after ovulation. In fact, this phenomenon is observed very rarely, because the egg has to travel a long way before it reaches the womb. In addition, during this period, the uterus is not always ready to accept the embryo, the thickness of the endometrium and the amount of accumulated nutrients insufficient for such an important mission. However, there are officially confirmed data that in exceptional cases, pregnancy can occur and end in a successful birth.

Late implantation occurs on the 10th day. This period is favorable for the IVF procedure. Quite often this is observed when a woman is at least 40 years old. At this age, late implantation of the embryo is not at all rare. On what day can the majority of women expect it? This usually happens on the 8-9th day after ovulation. The implementation process itself takes 2-3 days.

First sensations

Can you feel the attachment of the embryo to the uterus? Symptoms may not always be obvious, but if a woman is in harmony with her body, then she is able to recognize what is happening now. At first glance, only a tiny cell is introduced into the wall of the uterus, but, on the other hand, this dramatically changes hormonal background. That is why it is quite natural that unusual sensations can be traced.

Minor bleeding is the first and main symptom that accompanies the attachment of the embryo to the uterus. Symptoms can be obvious (for example, a blood stain appears on the linen, which can be mistaken for the onset of menstruation) and latent - in this case, the discharge becomes light brown or barely pink, so if you do not wear daily, you may not notice them on a dark underwear.

During the implantation period, abdominal pain, tingling and a feeling of heaviness may disturb. However, if a woman is expecting her main period, then it is quite possible that these symptoms will be regarded as PMS. The main symptom can be considered an increase in body temperature to 37-37.3 ° C. If you are building a graph basal temperatures, then you will definitely notice this jump.

However, everything is very individual. Someone does not notice any changes, so that the attachment of the embryo to the uterus is completely asymptomatic. Feelings can be blurry, and if a woman does not count the days before pregnancy and does not look for signs of her onset every day, then they can be completely ignored. There is nothing wrong with this, soon nature itself will tell you that it is time to prepare for the appearance of the baby.

The onset of pregnancy

It takes about 2-3 days for the embryo to go through the implantation stage. After that, they begin to appear clear signs onset pregnancy. It's a metallic taste in the mouth as well mild nausea. May cause dizziness and increased irritability, weakness. Someone notes an extraordinary emotional upsurge and a feeling of endless euphoria, others, on the contrary, depression and resentment towards others. These days it becomes obvious that the next menstruation is delayed. Plus, there is soreness of the mammary glands. All together is reliable signs that soon you will become a mother.
