Week 5. A small big shoot up

At first, the embryo is so small that it can only be seen under a microscope. However, during week 5 it multiplies its size by 40.

The baby will be unique. Your pregnancy has begun by the fusion of an ovum with a sperm, each with its own DNA. This union forms a series of 46 chromosomes that determine all the hereditary characteristics of the baby: sex, constitution, hair, eye colour, skin colour, features of their face and some of its personality traits. The DNA will determine its development during the 40 weeks of pregnancy and throughout life.
