Newborn girls bleed down there, this situation is called pseudo-menstruation, the main reason is: in the late stages of pregnancy, the mother’s estrogen into the body of the fetus, after the birth of the newborn baby, this hormone is suddenly interrupted, and then the phenomenon of pseudo-menstruation is produced, which belongs to the physiological phenomenon. Usually the amount discharged is not large and does not require any treatment, and it can disappear naturally in about a week. If the amount of discharge is relatively large, it is recommended to check the blood routine and coagulation function. If there is no discharge, or the child is crying, or there is a bulge in the vaginal area, it is possible that the menstruation is backing up into the uterus, which needs to be examined and treated in the hospital. Most children are fine.
