Postpartum hemorrhage is excessive bleeding following the birth of a baby. About 4 percent of women have postpartum hemorrhage and it is more likely with a cesarean birth. Hemorrhage may occur before or after the placenta is delivered. The average amount of blood loss after the birth of a single baby in vaginal delivery is about 500 ml (or about a half of a quart).

Abortion is legal in Great Britain at any time up to 24 weeks of pregnancy. The majority of abortions are carried out before 13 weeks, and most of the rest before 20 weeks. There are some exceptions.
