That. That is abnormal, so would be considered as dysfunctional uteirne bleeding. I don't know your age. If there is any chance you could have been pregnant and are having a miscarriage you need to be seen immediately. Sometimes stress or other issues can cause irregular periods. You may need to have your periods "re-cycled" with a hormone supplement to stop the bleeding. Please see a gynecologist for a complete evaluation. Also please be sure your pap smear is up to date.
