39 Weeks Pregnant
You may notice that your baby is not moving around very much -- he or she is in cramped quarters at this point! If you notice a complete lack of movement, talk to your healthcare provider.
Other fetal development that is occurring around week 39 of pregnancy includes the following:
- Toenails and fingernails have grown to the tips of the toes and fingers
- Your baby's arm and leg muscles are quite strong
- Your baby is practicing lung movements, while lung surfactant production increases
- Your baby continues to shed the fuzzy layer of lanugo hair
- Your baby sheds the vernix caseosa (the skin coating that covers a fetus to protect the skin)
- All of your baby's organs are ready to function outside of the womb.
During week 39 of pregnancy, the placenta will continue to supply your baby with antibodies. These antibodies will help your baby fight infection the first six months after birth. The umbilical cord that carried nutrients from the placenta to your baby is now 20 inches long and half an inch thick.
