Most women do not get their period right after delivery because the body indicators have not yet returned to normal and the uterine lining has not yet reached a state where they can get their period, so they will not get their period just after one month. The physiological recovery period takes about 56 days in the case of normal delivery and about 3 months in the case of cesarean delivery. It is recommended that if vaginal bleeding occurs just after the first full month, it is often not menstruation but abnormal bleeding, which may be caused by residual tissue in the uterus, infection in the uterine cavity, or drinking a lot of wine or using a lot of ginseng or antler tonic. .
