Vaginal bleeding is a normal physiological phenomenon if it occurs during menstruation. However, if abnormal vaginal bleeding occurs outside the menstrual cycle, women need to be examined and treated immediately. Because this can be a sign of many dangerous gynecological diseases that affect health and fertility.

Uterine bleeding in women usually only occurs during menstruation. However, due to some gynecological disorder, the bleeding may become abnormal compared to usual times. When there is abnormal vaginal bleeding, women need to see a doctor immediately for timely diagnosis, testing and treatment.

Both emergency contraceptive pills and daily hormonal pills have side effects that cause painless, non-cyclical vaginal bleeding. The next menstrual period will also often change due to the hormones in the body being affected.
