Having brown discharge does not always lead to abortion, it depends on what causes the brown discharge. If the brown discharge is caused by vaginitis, cervicitis, uterine fibroids and other diseases, it usually does not lead to fetal abortion. Therefore, patients with brown discharge should seek medical attention in time to determine the cause of bleeding and the developmental status of the embryo through examination. 1. It will not stop the fetus: if a pregnant woman has brown discharge, if it is caused by vaginitis, cervicitis, uterine fibroids and other diseases, it usually will not lead to fetal abortion. It is recommended to pay attention to observation, take proper rest, and if the bleeding does not ease, you can seek medical attention from the obstetrics and gynecology department for medication under the guidance of a doctor. 2. May be fetal abortion: brown discharge in early pregnancy with abdominal pain may be preterm miscarriage, if timely treatment for fetal preservation, may be successful, it will not stop. If the check progesterone value is low and no fetal heart and fetal bud is seen in ultrasound examination, it generally indicates embryonic abortion and there is no need to perform fertility preservation. Therefore, there are very many reasons why pregnant women have brown discharge, not necessarily embryonic abortion, which must be determined by observation and examination. If the fetus is abnormal, it can be detected and intervened in time.
