When a woman has an ectopic pregnancy, vaginal bleeding can persist or be intermittent as long as the gestational sac tissue is not removed. When a woman has an ectopic pregnancy, the gestational sac is attached to a location outside the uterine cavity. Therefore, the supply of nutrients is inadequate, which can cause the death or rupture of the embryo. When this happens, the woman will experience vaginal bleeding. When this happens, the bleeding is irregular, dark red or dark brown in color, and the amount of bleeding may be spotty, usually not exceeding the amount of menstruation. Observation of vaginal bleeding reveals that the amount of vaginal bleeding is not directly proportional to the severity of ectopic pregnancy. Some women have a lot of vaginal bleeding, just like menstruation, but others just bleed in dribs and drabs, and there is already a lot of pooled blood present in the pelvis, and hemorrhagic shock can be present in female patients. Generally speaking, the vaginal bleeding will only stop after surgery, or through conservative treatment, when the gestational sac of the ectopic pregnancy is removed, or dies and is completely killed, and the HCG drops to normal.
