Your Baby - 39 Weeks Pregnant

Pregnancy Week 39 The lanugo (that soft covering of hair) is mostly gone now and your baby will continue to gain weight, even up to the last week or two of pregnancy. He doesn't have much room to move in the uterus so movements may begin to slow. At this point, all the organ systems are developed and in place. Your baby is still building a layer of fat to help control body temperature after birth. The last part of development is the maturing of lungs. Your baby is ready to greet the world. He is approximately 20 inches and weighs a little over 7 pounds.

The bad news: the uterus is now pressing on your bladder so you'll be going to the bathroom even more often than before. Your uterus is now 7 to 8 inches above your navel.
