Two months after the miscarriage, there will be brown discharge, suggesting that there may be poor contraction of the uterus, or there may be residual tissue and fluid in the uterine cavity, and ultrasound is needed to determine whether there are abnormal echoes in the uterine cavity. If necessary, oral medication should be taken to help restore the uterus to its normal shape, along with blood tests and chorionic gonadotropin, as long as the chorionic gonadotropin is outside the normal range, indicating that the uterus has not returned to its normal shape after abortion. Avoiding the presence of abnormalities in the uterine cavity for a long period of time can affect future pregnancies and can also affect the contraction of the uterus, as well as cause the occurrence of infections and the chance of anemia. Even if the uterus is normal in shape, the HCG is normal and there is brown discharge, oral anti-inflammatory and hemostatic drugs should be taken to avoid irregular menstruation and pelvic inflammatory disease.
