    I was diagnosed with PCOS 13yrs ago, and I'm currently taking continuous birth control for 3 months at a time unless I experience breakthrough bleeding. Well, last night I started passing blood clots, and now I'm a little concern. I still feel the abdominal cramping, but wasn't passing anymore clots (right now). Is this normal?
    Jane Harrison Hohner, RN, RNP responded:
    Dear erikalinn: As you have correctly noted, breakthrough bleeding can be a common side effect both in regular and continuous regimens of birth control pills. Breakthrough bleeding can be heavy enough to prompt clots. Clots form when the bleeding is very brisk as the volume of flow exceeds the production of an enzyme that keeps menstrual flow liquid for easy passage out of the uterus.

    If you continue to have a super heavy flow accompanied by cramps let your GYN know. They may want you to take a short break (eg 3-7 days) then restart the continuous regimen.
