A pregnancy that bleeds with a brownish discharge can be caused by a preeclampsia, possibly an ectopic pregnancy, or have other gynecological problems. 1. Pre-eclampsia: bleeding after pregnancy may lead to miscarriage, but there are some patients with a favorable outcome. It is necessary to do active examination to monitor the development of the embryo. 2. Ectopic pregnancy: In some patients, the bleeding of pregnancy is caused by ectopic pregnancy. Some of the embryonic tissues of ectopic pregnancy are underdeveloped, which may affect the hormone level in the body. Some of them may lead to different degrees of shedding of endometrium for vaginal bleeding, and some of them may have sudden and vicious pelvic and abdominal hemorrhage. 3. Other gynecological problems: vaginal or cervical inflammation or tumor-related problems may cause bleeding symptoms. Therefore, if you are pregnant and bleeding, you need to go to the doctor as soon as possible for examination, or you need to do the corresponding treatment as soon as possible.
