At first the account goes on days a day the baby changes very much, gradually becoming like a small person. Then its development is slower, but almost every week in the body there are important changes.

1 day. Conception occurs when the spermatozoon meets the egg to form a single cell, a size slightly smaller than a grain of salt. This is the future baby, who inherited 23 chromosomes from his father and the same number from his mother. This little cell already contains a complex genetic plan that determines the sex of the baby, its height and even the color of the eyes.

5-9 day. During these several days the zygote grows into the mucous membrane of the uterine cavity and already begins to receive nutrition.
