The amazing can happen every day - near us, around and even inside us. And the most wonderful event, of course, can be considered the birth of a new life. From the tiny cell to develop a full-fledged and viable organism, which will grow and he will become the successor of the genus. But, despite the fact that in the process of conception two people participate, the carrier of a new life can only be a woman. Therefore, our article focuses more on the fair sex. Only you can by indirect signs guess what is happening now a great miracle, namely the attachment of the embryo to the uterus. On what day it happens, what signs are accompanied - this is what we will now talk about.
We will not dwell on this process in detail, just briefly run through to restore the entire logical chain. So, on a certain day of the cycle, the ovule begins its way to the uterus through the fallopian tubes. She will reach it anyway. Left unfertilized, here it will collapse, and another menstruation will occur. In this case, the layer of the endometrium that lines the uterus is also rejected. But with the beginning of the next cycle, everything will start all over again. The endometrial nutrient layer in the uterus will resume, a new egg will ripen, and with successful circumstances, pregnancy may occur.
To do this, now only one thing is necessary: the presence of viable spermatozoa, which reach the fallopian tubes and fertilize the egg cell.
Now it is no longer an egg cell, but an embryo begins its way to a place where it can develop over the next nine months. Takes a journey of seven to ten days, if you count from ovulation. The embryo will attach to the uterus soon enough. What day it will happen, the answer is unlikely to succeed. It all depends on the cycle of the woman and the day on which sexual intercourse took place. In addition, spermatozoa carrying the Y chromosome are more mobile and can more quickly achieve their goal, while its counterparts carrying the X chromosome (future girls) are slower, but they can live longer and wait for the egg to come out.
Now let's talk about what, in fact, is the attachment of the embryo to the uterus. On what day this happens - you can find out exactly, making an ovulation schedule. We will talk about this later, but a little later. So, the fertilized egg descends into the uterus and chooses a place for final fixation. On this day, she sheds a shiny coat to attach to the endometrium. It is called “trophoblast”.
The future mother may not yet guess what is happening in her body. Meanwhile, the villi are plunging deeper and deeper into the mucous membrane and secrete special enzymes. They contribute to the growth of the mucous membrane, which allows the embryo to dig deeper and deeper. Here he will get everything he needs for development: protection, food and oxygen.
The maternal organism tries to diagnose embryo attachment to the uterus. On what day this happens, we'll find out soon. If no genetic pathologies (among those that the body is able to recognize) are detected, the pregnancy continues. Otherwise, normal menstruation begins. 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, important conditions must be met. First of all - the endometrial layer in the uterus must have a certain thickness. Implantation is supported by a hormone of the corpus luteum called “progesterone”. Its main task is to stimulate the growth of the endometrium. In some cases, the shiny protective sheath may be too thick. This can create obstacles for successful “deployment”.
Types of implantation
In official science, implantation is classified into early and late. Separate both species depending on when the implantation of the embryo. What day does it happen? Early implantation occurs on the sixth or seventh day after ovulation. In fact, this phenomenon is very rare, because the egg has to go a long way before it reaches the womb. In addition, during this period, the uterus is not always ready to receive the embryo, the thickness of the endometrium and the amount of accumulated nutrients are insufficient for such an important mission. However, there are officially confirmed data that in exceptional cases, pregnancy can occur and end in a safe birth.
Late implantation occurs on the 10th day. This period is favorable during the IVF procedure. This is often observed when a woman is at least 40 years old. At this age, late implantation of the embryo is not uncommon. On what day can she be waiting for the bulk of women? This usually happens on the 8-9th day after ovulation. The implementation process itself takes 2-3 days.
Can the embryo attachment to the uterus be felt? Symptoms may not always be obvious, but if a woman is in harmony with her body, she is able to recognize what is happening now. At first glance, only a tiny cell is implanted into the uterus, but, on the other hand, it dramatically changes hormones. That is why the fact that it is possible to track unusual sensations is quite natural.
Minor bleeding is the first and main symptom that accompanies embryo attachment to the uterus. Symptoms can be pronounced (for example, a stain of blood appears on the underwear, which can be mistaken for the beginning of menstruation) and latent - in this case, the discharge becomes light brown or barely pink, so that if you do not wear the daily, you can not notice them on the dark underwear.
During the implantation period, abdominal pain, tingling, and a feeling of heaviness may disturb. However, if a woman expects major menstruation, 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 o C. If you build a graph of basal temperatures, then you will certainly notice this jump.
However, everything is very individual. Someone does not notice any changes, so that the embryo attaches to the uterus completely asymptomatically. Feelings can be blurred, and if a woman does not count the days before pregnancy and every day does not look for signs of its occurrence, then it is quite possible to ignore them. Nothing wrong with that, soon nature itself will tell you that it's time to prepare for the appearance of the baby.
Onset of pregnancy
It takes about 2-3 days for the embryo to undergo the implantation stage. After that, clear signs of the onset of pregnancy begin to appear. It is a metallic taste in the mouth, as well as a slight nausea. May be disturbed by dizziness and irritability, weakness. Someone notes an unusual emotional rise 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 pain in the mammary glands. All together - these are reliable signs that you will soon become a mother.
