The timing of bleeding caused by an ectopic pregnancy does not have a specific timeframe.

Most ectopic pregnancies result in irregular vaginal bleeding after the death of the pregnancy tissue. The color of the blood is usually dark red or deep brown, and generally, the amount of bleeding is less than that of a normal menstrual period. However, a minority have heavier bleeding, similar to menstrual flow. Vaginal bleeding may contain decidual cast and fragments, caused by the shedding of the uterine lining. Vaginal bleeding only stops after the removal of the lesion or during conservative treatment when the trophoblastic cells are completely necrotic and absorbed; thus, bleeding from an ectopic pregnancy generally lasts a long time. Anti-inflammatory treatment might be necessary to avoid secondary infections that could affect future pregnancies.
