When a mother experiences hemorrhage (bleeding) during labor, it may represent significant clinical signs to her overall health and life-threatening warning and needs to be treated immediately. Bleeding can be classified into three periods: before, throughout labor, and after birth.

A cesarean section is a major surgical procedure performed on the lower abdomen and uterus to deliver a baby. The healing process of the cesarean scar depends on the woman's health, and typically the scar will fully heal within 3 months after childbirth. However, this scar is closely related to future pregnancies and deliveries. Especially when undergoing a third cesarean, the risks increase.
