Who am I?

What happens in weeks 9 to 12?

From week 9 (the 11th week of pregnancy) the developing embryo is called a fetus. The size of its body catches up with the outsized head, making it look more human, although the legs are still slightly short. Protected by the amniotic fluid, the fetus can move around and flex its limbs. By 12 weeks, it can hear sounds, and its skin is sensitive to touch.
