Abnormal vaginal bleeding is any bleeding that is outside of normal menstrual periods, or any bleeding after menopause. A normal menstrual period occurs on a regular predictable schedule (that can be anywhere from every 3 to 5 weeks), lasts no longer than a week at a time, and is not heavy enough to interfere with a woman's normal activities. Bleeding in between periods, bleeding after sex and ANY bleeding after menopause is consider abnormal vaginal bleeding, and should be evaluated by a gynecologist.
