For several days after giving birth, women will generally experience blood coming out of their genitals. This is what is referred to as puerperal blood or lochia. Puerperal blood or lochia similar to heavy menstruation, only the amount is more. Puerperal blood from the vagina is the body's way to remove the lining of the uterus and blood after childbirth. This is something that happens to every woman after giving birth. The Origin of Puerperal Blood When the fetus is in the uterus, the placenta functions to feed the fetus. The placenta attaches to the uterine wall and contains arteries and veins. When the placenta is released from the uterus, there are parts of blood vessels in the uterine wall where the attached placenta is torn, then begin to flood the uterus with blood. After the placenta has been removed, the uterus will contract until the torn blood vessels close and reduce bleeding. The remaining blood in the uterus will continue to come out for at least 2-6 weeks aft
