Implantation bleeding: on what day and how long is

The vast majority of women do not know that one indication of the onset of pregnancy is implantation bleeding.

In general, signs of pregnancy are manifested as early as the second week after sexual intercourse and during the fertilization of the egg, that is, before the first delay.

It turns out that implantation bleeding is one of the first physiological signs of pregnancy.

It should be noted that, firstly, not all women have this feature, and secondly, even if it is, it is often not paid attention to it, without attaching special importance.

What is implantation bleeding?

The very word implantation of means introduction of . In this case, we are talking about the introduction of a fertilized egg into the wall of the uterus. In the process of ovulation, the egg leaves the mature ovarian follicle into the abdominal cavity, then flows through the uterine tube into the uterine cavity. From the uterine tube to the uterus, the egg passes within five days, the implantation itself lasts approximately two days after the egg enters the uterus. Thus, the implantation of a fertilized egg is, in fact, the first contact of the fetus with the maternal body. Before this egg is almost in "free flight", or rather, swimming in the body of a woman, so any signs of pregnancy are excluded. The egg is at this time tiny and almost invisible, but as soon as it penetrates into the wall of the uterus, it begins to increase, and from now on it can be called an embryo.

It is during the implantation of the egg in the wall of the uterus that may appear. Implantation bleeding in the form of brown discharge - only one or two drops. At the same time, some women feel the pulling of spasmodic pains in the lower abdomen. Is there always bleeding at the time of implantation? No not always. Only in the event that there is a microscopic damage to the wall of the uterus.

How long does the implantation bleed?

Implantation bleeding usually occurs about 7 days before the estimated start of the next monthly cycle. Therefore, women sometimes do not take these drops of blood seriously, taking them for heralds of menstruation. Another thing, if the selection appeared a day or two before the start of a new cycle: here already assert that this is a sign of implantation of the egg - it is impossible.

At the time of implantation, some women, except for excretions and some physical sensations, notice the so-called westing of the temperature curve on the graph of basal temperature measurement. This happens 6-9 days after ovulation. But this kind of zapping does not happen to all women, so his absence does not say anything.

In fairness, it should be noted that the described symptoms - blood secretions, temperature changes - do not always indicate the presence of the process of implantation of the ovum, and hence the pregnancy. Sometimes these symptoms are associated with very different factors. But, at least, if you notice such signs, you can already assume that the pregnancy has come, and make the appropriate test.
