Nesting: what it is, what symptoms it involves and when to take the pregnancy test
Nesting, also called "implantation" or "nesting", is one of the first stages leading to pregnancy: it is the moment in which the embryo implants itself in the endometrium, the internal tissue of the uterus.
During ovulation, an egg is released into the fallopian tube, which connects the ovaries to the uterus: it is in this path that it can meet the spermatozoa and be fertilized. When the egg is fertilized, a zygote is formed which, increasing its volume, reaches the uterus in the form of a "blastocyst". Three days after fertilization, the embryo is made up of sixteen cells, while on the sixth day it reaches about 180. Once it reaches the uterus it is received in the endometrium: the nesting has taken place.
Let's take a closer look at how this process takes place, what the symptoms are and how long after nesting is it possible to take a reliable pregnancy test and why it is necessary to wait. Meanwhile, here is a very useful video to learn how to calculate all your fertile days every month:
How and when does nesting take place?
The nesting phase is relatively short, lasting a whole week, in which it is possible to distinguish three different moments. At first we see the embryo approaching the endometrium and approaching the wall of the uterus. This first part of the process is the so-called "adhesion" phase, favored by the adhesion molecules of the endometrium.
In a second moment, the "attachment to the endometrium" occurs, while finally the so-called "invasion" occurs, in which the embryo penetrates inside the endometrium itself and implants itself definitively. period, begins to draw nourishment from the mother's uterus.
Nesting is a fundamental moment for pregnancy to begin and does not manifest itself in the same way in all women: there may be early or late nestings. What is certain is that it is precisely from then on that the future mother begins to produce the hormone Beta Hcg, useful and very important for the growth of the fetus, together with progesterone which will keep the uterus in good health by providing the baby with the necessary nourishment for the development.
What are the symptoms of nesting?
The symptoms of nesting can be different and vary greatly from woman to woman. In some cases, you may not even experience any symptoms. Consequently, if you wish to become pregnant, do not worry if in the period of fifteen days from ovulation you have not experienced any particular symptoms: it does not mean that you cannot be pregnant anyway!
The most common and, above all, evident symptom of nesting are the so-called "implantation losses". In fact, when the embryo implants itself in the uterus, blood losses very similar to those of the menstrual cycle may occur. but which - unlike the latter - are less abundant and shorter or discontinuous. In fact, it is not a real menstrual cycle, but the expulsion of fibrin due to the implant itself.
Often, women who did not anticipate a pregnancy happen to mistake these implant losses for the menstrual cycle itself, also because they tend to arrive at about the same days of the month in which the period should have come. In this case, it will be enough to check the losses, which - in case of nesting - are clearer and do not last more than three days.
During the nesting period it is also possible to begin to feel the classic first symptoms of pregnancy: tension and pain in the breast, morning sickness, vomiting, cramps in the uterus area, muscle aches and, in general, widespread pain (especially in the area of the lower abdomen), a sense of tiredness and exhaustion, even at rest, constipation, nervousness and mood swings, problems with insomnia.
Another possible symptom to keep in mind if you are trying to get pregnant is the increase in body temperature when you wake up: it is common for this increase to occur during the entire week of nesting, but not beyond.
How many days after nesting can you take the pregnancy test? Here is the calculation!
If you are trying to calculate the days of the nesting, it is easy to say. The nesting process, as we have seen, begins between the sixth and seventh day of conception and ends by the thirteenth day. Since fertility female, as we know, is maximum in the three days preceding ovulation and on the day of ovulation itself, we must imagine that conception took place in that specific window of about four to five days.
Before letting yourself be enchanted by false myths regarding conception and starting your calculation of the period of fertile days and nesting days, take a "look at this video that Alfeminile has created for you because it may be useful for you:
Pregnancy tests begin to be reliable only after the first day of delay in the cycle, since they measure the Beta hcg value in the urine, which continuously increases in the days following nesting. Although there are more sensitive pregnancy tests, able to give an answer already around the twelfth day after ovulation, it is always good to wait for the delay to get a more reliable result.
If you are in a hurry to find out if you are pregnant, however, you can request a blood Beta hcg test, a test that can be performed starting from the ninth day after ovulation. However, it will still be useful to take the test after the first day of delay in the menstrual cycle to confirm the result. Good luck, we at Alfemminile are with you!
