Amazing can happen every day - next to us, around and even inside us. And the most wonderful event, of course, can be considered the birth of a new life. From a tiny cell it is necessary to develop a full-fledged and viable organism that will grow and become a successor of the genus. But, despite the fact that during the conception involves two people, the carrier of a new life can only be a woman. Therefore, our article focuses more on the fair sex. Only you can guess by indirect signs that now there is a great miracle, namely, attachment of the embryo to the uterus. On what day it happens, what signs are accompanied - we will now talk about this.
The process of fertilization
We will not dwell on this process in detail, only briefly go over to restore the entire logical chain. So, on a certain day of the cycle, the egg on the fallopian tubes starts its way to the uterus. She will reach her anyway. Remaining unfertilized, here it will collapse, and the next menstruation will occur. In this case, the layer of the endometrium, which lining the uterus, must also be rejected. But with the beginning of the next cycle, everything will start anew. The nourishing layer of the endometrium in the uterus will resume, a new egg will ripen, and with successful coincidences of circumstances pregnancy may occur.
For this, only one thing is needed now: the presence of viable spermatozoa that will reach the fallopian tubes and fertilize the egg.
Now no longer an egg, and the embryo begins its journey to a place where it can develop over the next nine months. It takes a journey of seven to ten days, if taken from ovulation. Soon enough, the embryo will attach to the uterus. On what day it happens, it is unlikely to answer unequivocally. It all depends on the cycle of the woman and the day in which the sexual act occurred. In addition, spermatozoa carrying the Y chromosome are more mobile and can reach their goal faster, while his fellow X-chromosome-bearing (future girls) are slower, but can live longer and wait for the egg to exit.
And now let's talk about what, in fact, is the attachment of the embryo to the uterus. On what day it happens - you can accurately find out by plotting the ovulation. We'll talk about this later, but a little later. So, the fertilized egg descends into the uterus and chooses a place for final fixing. On this day, she throws off a shiny shell to attach herself to the endometrium. It is called "trophoblast".
The future mother may not yet know what is happening in her body. And at this time the villi are getting 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 get everything he needs for development: protection, nutrition and oxygen.
Mechanisms of protection
The maternal organism tries to diagnose the attachment of the embryo to the uterus. On what day it happens, we will find out soon. If there are no genetic pathologies (from among those that the body is able to recognize), then the pregnancy continues. Otherwise, the usual menstruation begins. This process is completely painless, the woman does not even suspect what happened in her body.
Conditions for successful implantation
To ensure that the embryo is attached to the uterine wall, important conditions must be observed. First of all, the endometrial layer in the uterus should have a certain thickness. The implantation is supported by the hormone of the yellow body 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 to successful "implementation".
Types of implantation
In the official science, implantation is classified into early and late. Separate both species depending on when the implantation of the embryo occurs. On what day does it 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 overcome a long way before it reaches the bosom. In addition, during this period the uterus is not always ready to receive the embryo, the thickness of the endometrium and the amount of stored nutrients are insufficient for such an important mission. However, there are officially confirmed data that in exceptional cases, pregnancy can occur and result in a safe delivery.
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 embryo implantation is by no means rare. On what day can you wait for the bulk of women? Usually it occurs on the 8th-9th day after ovulation. The process of implementation takes 2-3 days.
Can I 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, she is able to recognize what is happening now. At first glance, only a tiny cell penetrates into the uterine wall, but, on the other hand, it dramatically changes the hormonal background. That is why it is quite natural that you can track unusual sensations.
Minor bleeding is the first and main sign that accompanies the attachment of the embryo to the uterus. Symptoms can be obvious (for example, a spot of blood appears on the underwear, which can be taken as the beginning of menstruation) and latent - in this case, the discharge becomes light brown or barely pink, so if you do not wear a daily routine, you may not notice them on the dark underwear.
During the period of implantation, pain in the abdomen, tingling and feeling of heaviness can be disturbed. However, if a woman expects a major menses, it is possible that these symptoms will be regarded as PMS. The main symptom can be considered a rise in body temperature to 37-37.3 o C. If you are building a graph of basal temperatures, then surely note this jump.
However, everything is very individual. Someone does not notice any changes, so that the embryo does not asymptomatically attach to the uterus. Sensations can be blurred, and if a woman does not consider the days before pregnancy and does not look for signs of her offense every day, then they can be completely ignored. There is nothing terrible in this, soon nature itself tells you that it's time to prepare for the appearance of the baby.
The onset of pregnancy
About 2-3 days it takes to ensure that the embryo has passed the stage of implantation. After this, obvious signs of pregnancy begin to appear. This is a metallic taste in the mouth, as well as mild nausea. May disturb dizziness and increased irritability, weakness. Someone notes an unusual emotional rise and a sense of endless euphoria, others, on the contrary, are depressed and resentful towards others. These days it becomes obvious that the next menstruation is delayed. In addition, there is soreness of the mammary glands. All together - these are reliable signs that soon you will become a mother.
