The first trimester begins at conception and lasts until the end of week 12. During this time, the fertilized egg grows and develops into an embryo. By week 12, the embryo has grown to the size of a plum and has all of its major organs and body parts. The baby’s heart has already begun beating and can be seen on an ultrasound.

By week 20, the baby is about the size of a banana and can be felt moving around in the womb. The mother’s belly also begins to visibly grow during this time.
