Your Pregnancy Week by Week: Weeks 35-40

Week 39

Baby: Your baby's arm and leg muscles are strong, and toenails and fingernails are in place. The baby's head has dropped into the mother's pelvis -- a head-down position lets you breathe a little easier.

Mom-to-be: You're probably feeling quite large and uncomfortable. Your uterus has filled your pelvis and most of your abdomen, pushing everything else out of the way. Your center of gravity has shifted, so you may feel clumsier than usual.

Tip of the Week: Watch for signs of labor, but don't get too obsessed. It could happen soon or still be a week away. Some differences between false labor and contractions: False labor pains usually concentrate in the lower abdomen and groin, while true labor pains may start in the lower back and may spread through the entire abdomen. Real labor also becomes stronger and more powerful as time passes.

Week 40

Baby:  Boys often tend to weigh a little more than girls. More lanugo falls out, but some may remain at birth on the baby's shoulders, folds of skin, and backs of ears.

Mom-to-be: It's almost time! Birth should happen soon now, but don't worry if your due date comes and goes. Only 5% of all babies are born exactly on the predicted due date. It may be more difficult for you to get a good night's sleep, because it's hard to find a comfortable position. Still, try to rest as much as possible, with your feet up if you can.

Tip of the Week: If you think you're in labor, don't eat. Even something light in your stomach can cause nausea.

What's Happening Inside You?

Your baby continues to grow and mature. The lungs are nearly fully developed. Your baby's reflexes are coordinated so he or she can blink, close the eyes, turn the head, grasp firmly, and respond to sounds, light, and touch.

You should still feel movement every day. Your baby's position changes to prepare itself for labor and delivery. The baby drops down in your pelvis, and usually his or her head is facing down toward the birth canal.
