Placenta accreta usually is not diagnosed until after the birth of the baby. In normal pregnancies, the placenta typically will deliver within 20 minutes without special procedures. If the placenta does not deliver on its own, then the obstetrician or midwife will attempt to manually remove the placenta. During this procedure, the provider places their hand into the uterus and tries to separate the placenta. In normal placentation, the provider is able to find the natural division between the uterus and placenta.
