If there is still bleeding one month after the birth of a baby, women should go to the hospital for gynecological ultrasound and blood test for routine blood, coagulation function and human chorionic gonadotropin level. If the chorionic gonadotropin and coagulation function are within the normal range, and the gynecological ultrasound shows that there is no foreign body in the uterine cavity, give hemostatic drugs such as blood flow breakers, Bao Gong hemostatic granules and cefradin capsules for treatment. Pay attention to proper rest, do not overexert yourself, do not eat spicy and stimulating food. If there is a foreign body in the uterine cavity, it is necessary to do the treatment of uterine clearance and send the cleared foreign body to pathological laboratory to clarify the nature of the lesion and then treat it symptomatically. In rare cases, if a woman’s uterus is slightly enlarged and the level of chorionic gonadotropin is increased by blood sampling, it can also occur in postpartum trophoblastic disease and methotrexate treatment needs to be given.
