Your Baby's Development
Your baby now weighs about 2 pounds, 7 ounces (1,100 grams) and measures about 10 inches (25 centimeters) from crown to rump. At your next prenatal appointment, your health care provider may inform you whether your baby is head first or feet or bottom first (called breech position) in the womb. If you feel the baby's head pushing against your cervix, he or she is probably in the head first position. Babies who are in the breech position may need to be delivered by cesarean section. Your baby still has 2 months to change position, though, so don't worry if your baby is in the breech position right now. Most babies will switch positions on their own.

The folds and grooves of your baby's brain continue to develop and expand. In addition, your baby continues to add layers of fat and has continued hair growth.

Your Body
Get ready to be seeing a lot of your health care provider's office. Starting this week, you'll probably be visiting your doctor or midwife every other week instead of every month. One test your health care provider may do is a blood type test. If your blood type is Rh negative, you'll have one Rh-immune globulin shot now, and a second shot soon after delivery. Rh-immune globulin prevents complications (such as jaundice and anemia) in case your baby's blood, which may be Rh positive, mixes with yours, which can cause an immune reaction against the baby's red blood cells, leading to jaundice with possibly severe anemia.
