First stage: Begins from the onset of true labor and lasts until the cervix is completely dilated to 10 cm.
Second stage: Continues after the cervix is dilated to 10 cm until the delivery of your baby.
Third stage: Delivery of your placenta.
The third stage is the delivery of the placenta and is the shortest stage. The time it takes to deliver your placenta can range from 5 to 30 minutes.
After your baby is born and the umbilical cord is cut, there is usually a lull for several minutes. Then your uterus starts contracting again. These contractions are not as strong as pushing contractions. You may not be aware of them because you may be paying attention to your baby. These contractions separate the placenta from the wall of your uterus.
