Pregnancy Week 16
This week of pregnancy, your baby is a little over 4 1/2 inches in length and weighs about 2 1/2- 3 ounces. Fine lanugo hair covers your baby's body and head. Gender is recognizable now during an ultrasound exam and you can also see your baby's movements and possibly the sucking reflex as your baby sucks his or her thumb. More below:
Changes in You:
You can easily feel your uterus below your belly button and you've most likely gained 5-10 pounds by now. This would be a good time to learn to sleep on your side, since you shouldn't lie directly on your back because it can place the uterus on top of major blood vessels, which can decrease circulation to your baby. Lying on your stomach isn't a good idea either, since it puts pressure on your growing uterus. So, invest in a pregnancy pillow or a body pillow for support.
