Placenta Previa. The placenta develops in a womanâs uterus during pregnancy. This sac-like structure provides the developing baby with food and oxygen. It also removes waste products from the babyâs blood. The placenta is also referred to as âafterbirth,â for it exits the body after the baby is born. During pregnancy, the placenta moves as the uterus stretches and grows. It is very normal for the placenta to be low in the uterus in early pregnancy. But as the pregnancy continues, the placenta typically moves to the top of the uterus. By the third trimester, the placenta should be near the top of the womb, so the cervix has a clear path for delivery.
