First Signs of Development: Your Baby in the Third Week of Pregnancy
In the third week of pregnancy, the embryo begins to show clearer signs of development. Although still tiny, the cells begin to organize and form the initial structures of organs. This is a crucial period where the embryo implants firmly in the uterus and begins to form the placenta, which will be vital for the exchange of nutrients and waste between mother and baby. This is the beginning of an incredible journey full of development and growth.
