What is abnormal uterine bleeding?
Abnormal uterine bleeding is any bleeding from the uterus (through your vagina) other than your normal monthly period. Having extremely heavy bleeding during your period can also be considered abnormal uterine bleeding. Very heavy bleeding during a period and/or bleeding that lasts more than 7 days is called menorrhagia (say: “men-oh-raj-ee-ah”). Women who have menorrhagia may, for example, bleed enough to soak through 1 or more tampons or sanitary pads every hour.
