The first day of pregnancy is considered the first day of the last period because most women cannot know for sure when their most fertile day was, and it is also not possible to know the exact day of fertilization since sperm can survive up to 7 days inside a woman's body.

Technically, in the first two weeks the woman is not pregnant because she has not yet ovulated, however, the uterus is getting ready and, in these weeks, the lining of the uterus, called the endometrium, thickens to receive the embryo, in case fertilization occurs.

Ovulation occurs between the 2nd and 3rd week and, if the spermatozoa find the egg, they can fertilize it, starting to divide and giving rise to the embryo, which will reach the uterus and implant, process known as nesting, in one of its thick walls.

Baby development

After conception, the developing embryo provides information to the brain about its existence, through the Beta HCG hormone, which inhibits the next menstruation. In addition, the Beta HCG hormone also maintains high progesterone levels throughout pregnancy, which are essential to prevent contractions during pregnancy and premature expulsion of the embryo.

Since there is still no placenta, the embryo behaves independently of the mother, however, it is already dependent on the mother's body to receive the necessary shelter for its development. The placenta normally develops around 12 weeks of gestation, when the baby's needs become more demanding, requiring more blood, oxygen and nutrients.

Baby size

The embryo is still very small, measuring approximately 0.15 mm, being smaller than a chia seed.
