39 Weeks Pregnant
You're 39 weeks pregnant
and your baby is about 20 inches long and weighs about 7.5 pounds. The head is about 4 inches in diameter. Your baby has reached his final birth position and it's cramped inside your uterus.
Your baby's kicks and movements may seem less forcefull, this is because of the limited space in your uterus. You may want to monitor baby's movements from time to time and do a fetal kick count. Basically making sure that baby is moving at least 10 times within 2 hours. When you pay close attention, you may notice baby moving more than 10 times in less than 2 hours. Sometimes babies can sleep up to four hours at a time, but it shouldn't be more than 4 hours.
Your body is still making amniotic fluid, but levels may decrease a little because the absorption might happen faster than the amount you make.
Although most of the downy hair should be gone by now, you may find a little on your baby's body, but don't worry, this will disappear on its own in time.
When your baby is born and takes his first breath of fresh air, the umbilical cord which is about 1/2 an inch thick, will stop working. Baby's breathing will trigger changes in the heart that will force all the blood to go through the lungs.
Once the umbilical cord is cut, baby will be an independent human being and must perform all of his body functions on his own.
Your baby will get antibodies from your body that give his immune system a boost.
