The third stage involves delivery of the placenta (afterbirth). It is the shortest stage, lasting 5 to 30 minutes. Contractions will begin 5 to 30 minutes after birth, signaling that it's time to deliver the placenta. You might have chills or shakiness. Labor is over once the placenta is delivered. Your doctor will repair the episiotomy and any tears you might have. Now, you can rest and enjoy your newborn!
