How the embryo develops in the first month of pregnancy: photos of the first month of pregnancy by weeks and days, video
Most women in the first monthPregnancy even do not know about their interesting situation. The shape and size of the abdomen are practically unchanged. However, all the metamorphoses on this term are internal, and not external. Development of the embryo goes through several stages. The embryo gradually forms, changing every week. It is impossible to trace it independently, but it is easy to imagine how the new life is born in pictures.
An embryo, an embryo, or a fetus: how does it form
The period of pregnancy is counted from the moment of the last menstruation. In this case, conception and the preceding ovulation occur approximately 14 days later.
The first week is marked by the course of menstruation. In this case, the woman's body is adjusted to its new position. Of the many eggs, only 1 begins to ripen. The mucous surface of the uterus gradually departs. A new layer forms on the site of the rejected tissues. As such, there is no embryo yet. Even on ultrasound it is not always possible to trace these changes.
The second stage is indicated by the manifestation of the ovum,Which can be called a leader. It is concentrated in a kind of bubble that is present on the ovary. The end of this stage is the flow of ovulation. The vesicle bursts, after which the egg leaves the abdominal cavity of the woman. Again, it can not yet be called a fruit, since it is a very small formation, as can be seen from the photo, penetrating into the fallopian tube. For 1-2 days the future child is kept there. After that, it remains only to wait for spermatozoa. There are many sketchy videos about how their "meeting" occurs. Below is one of them.
