Patients with ectopic pregnancy do not necessarily bleed every day. The most important clinical manifestations of ectopic pregnancy are: lower abdominal pain and irregular vaginal bleeding. Therefore, for patients with ectopic pregnancy, it is not necessarily the case that bleeding occurs every day. Ectopic pregnancy patients sometimes show a small amount of vaginal bleeding, and some show an increase in the amount of vaginal bleeding, even more than the amount of menstruation. Clinical manifestations are varied, and so are the clinical manifestations of vaginal bleeding, some manifesting a small amount of inexhaustible vaginal bleeding, some manifesting a relatively large amount of bleeding, and some manifesting a large amount of bleeding in the first few days, followed by a small amount of bleeding in the next few days, or stopping for a few days and then bleeding occurs again. All in all, the bleeding of ectopic pregnancy is very strange.
