Abnormal uterine bleeding has many causes. It is sometimes caused by changes in hormone levels. It can also be caused by problems such as growths in the uterus or clotting problems. In some cases the cause of the bleeding isn't known. You may have abnormal uterine bleeding if you have one or more of the following symptoms: 1  You get your period more often than every 21 days or farther apart than 35 days. 2  Your period lasts longer than 7 days (normally 4 to 6 days). 3  Your bleeding is heavier than normal.
Bleeding may be abnormal because of how heavy it is or when it happens, such as after you have gone through menopause, between periods, or any other bleeding that is longer or heavier than is normal for you. Uterine cancer may also cause other symptoms, such as pain or pressure in your pelvis. If you have bleeding that is not normal for you, especially if you have already gone through menopause, see a doctor right away. Also see a doctor if you have any other signs or symptoms for two weeks or longer.
