The appearance of blood in the uterine cavity after childbirth may be a sign of a weaker body and poor uterine contraction after childbirth. When this happens, women can take oral biochemical pills or motherwort to help the uterus contract and help the blood in the uterine cavity to be discharged. You can also massage the uterus with your hands on the lower abdomen to promote uterine contraction. For women who are breastfeeding after giving birth, the baby sucking on the breast and stimulating the nipple can also reflexively cause the uterus to contract, which helps to expel the blood in the uterine cavity. Some women think that resting in bed after giving birth is good for the elimination of vaginal discharge, but this is not the case. Lying in bed all the time may cause the vaginal discharge to be unable to come out and accumulate in the uterine cavity. Therefore, it is important to get out of bed in moderation after delivery to help discharge the blood in the uterine cavity.
