Week 34: Baby's fingernails grow

Thirty-four weeks into your pregnancy, or 32 weeks after conception, your baby's fingernails have reached his or her fingertips.

By now your baby might be nearly 12 inches (300 millimeters) long from crown to rump and weigh more than 4 1/2 pounds (2,100 grams).

Week 35: Baby's skin is pink and smooth

Thirty-five weeks into your pregnancy, or 33 weeks after conception, your baby's skin is becoming pink and smooth. His or her limbs have a chubby appearance.

Week 36: Baby takes up most of the amniotic sac

Thirty-six weeks into your pregnancy, or 34 weeks after conception, the crowded conditions inside your uterus might make it harder for your baby to give you a punch. However, you'll probably still feel lots of stretches, rolls and wiggles.

Week 37: Baby might turn head first

Thirty-seven weeks into your pregnancy, or 35 weeks after conception, your baby has a firm grasp.

To prepare for birth, your baby's head might start descending into your pelvis. If your baby isn't head down, your health care provider will talk to you about ways to deal with this issue.

Week 38: Baby's toenails grow

Thirty-eight weeks into your pregnancy, or 36 weeks after conception, the circumference of your baby's head and abdomen are about the same.

Your baby's toenails have reached the tips of his or her toes. Your baby has mostly shed all of his or her lanugo.

By now your baby might weigh about 6 1/2 pounds (2,900 grams).

Week 39: Baby's chest is prominent

Thirty-nine weeks into your pregnancy, or 37 weeks after conception, your baby's chest is becoming more prominent. For boys, the testes continue to descend into the scrotum. Fat is being added all over your baby's body to keep him or her warm after birth.

Week 40: Your due date arrives

Forty weeks into your pregnancy, or 38 weeks after conception, your baby might have a crown to rump length of around 14 inches (360 millimeters) and weigh 7 1/2 pounds (3,400 grams). Remember, however, that healthy babies come in different sizes.

Don't be alarmed if your due date comes and goes with no signs of labor starting. Your due date is simply a calculated estimate of when your baby will be 40 weeks. It does not estimate when your baby will arrive. It's normal to give birth before or after your due date.
