Although in obstetric practice and it is believed that in two weeks the pregnancy has not yet occurred (the actual pregnancy does not count as pregnancy), the embryo in 2 weeks already begins to live its life and develop according to its term. After all, since the first hours of conception, the fetal egg has developed consciousness.
Immediately after the fertilization of the egg, which takes place in the fallopian tube, the zygote -a fertilized egg begins to split . After making the way through the fallopian tube, on the fourth day the fetal egg turns into a blastocyst. In the uterus of the uterus, the blastocyst approaches the implantation site of the egg - insertion into the uterus, this process lasts about 2 days. Egg by this time settles on the mucous membrane of the uterus and with the help of chorionic villi firmly attached to the mucous uterus.
The human embryo is 2 weeks old
The human embryo, aged 2 weeks, is in the Graaf bubble. He did not change much after the conception process, he has already formed extra-germplasm organs - amnion, chorion, yolk sac, which he provides all the necessary conditions for further development. At 2 weeks, the fetus forms the nuclei of the cell and cytoplasm. By the end of 2 weeks, the embryo becomes a mature egg, which has a nucleus formed by the cytoplasm, a shiny transparent shell, and is "decorated" with a crown of epithelial cells.
2 weeks gestation - fetal size
As studies show, the size of the embryo at week 2 is still impossible to measure, as well as the weight of the baby in 2 weeks. The first size, which can be determined - 0.15 mm, was recorded in the third week of pregnancy, and weight - 1 g - only at week 8.
Development of the fetus in 2 weeks
To maintain pregnancy, it is necessary to follow the drinking regimen, the diet regime, i.e. provide the future child with everything necessary for proper development. Under unfavorable conditions for the development of an embryo in the age of 2 weeks may not be implanted and will come along with menstruation. And the woman will never know that she was pregnant.

How does the fetus look like 2 weeks?
To find out, it's enough to make an ultrasound that will not only show how the embryo looks, but also precisely determine the length of the pregnancy. Despite the fact that the embryo is not yet visualized , at the time of ultrasound it is possible to determine the heart rate.
The embryo has already been conscious for 14 days, its vital organs are formed, its heart can be heard. This is not just an embryo. This is your future baby, who will be born in 38 weeks.
