You may get small tear in the region of vaginal opening during the delivery and if your vaginal opening is very close, the doctor may make a small cut around it, to increase the tear (episiotomy). Mostly, these tears need stitches but they dissolve during the healing process. These tears may make you uneasy for a few days.
Generally, the placenta comes out easily after delivery, while in few cases, the doctor removes it manually under anaesthesia when it does not come out on its own. Also, some women lose small amount of blood during the delivery, but if the amount of blood loss is greater, blood transfusion may be required.
