Pregnancy a Week by Week Guide

• Pregnancy week by week at week twenty. We are now about half way through the pregnancy and the baby now reacts as newborn with time to sleep and time wake. The tiny ones start to grow scalp hair. If the baby is a girl then she will develop her uterus at this time.
• Pregnancy week by week at week twenty-one. This is the week that the rapid growth phase begins to slow down. The little heart grows stronger and the legs are reaching their relative proportions.

• Pregnancy week by week at week twenty-two. Your baby is very thin still even though it probably weighs a pound. Now it is the brain that begins to grow rapidly. If your baby is a boy, his testes have begun their descent from the pelvis to the scrotum.
