Abnormal vaginal bleeding is any vaginal bleeding unrelated to normal menstruation. This type of bleeding may include spotting of small amounts of blood between periods — often seen on toilet tissue after wiping — or extremely heavy periods in which you soak a pad or tampon every one to two hours for two or more hours.

Normal vaginal bleeding, or menstruation, occurs every 21 to 35 days when the uterus sheds its lining, marking the start of a new reproductive cycle. A menstrual period may last for just a few days or up to a week. Your flow may be heavy or light and still considered normal. Menstrual cycles tend to be longer for teens and for women nearing menopause, and menstrual flow may also be heavier at those ages.
