Menstruation, or period, is a woman's monthly bleeding. Abnormal vaginal bleeding is different from normal menstrual periods. It could be bleeding that is between periods, is very heavy, or lasts much longer than usual. It also includes bleeding that happens before puberty or after menopause. Causes can include:
- Uterine fibroids or polyps
- Hormone problems
- Hormone pills, such as birth control pills and hormone replacement therapy (menopausal hormone therapy)
- Cancer of the cervix, ovaries, uterus or vagina
- Thyroid problems
Bleeding during pregnancy can have several different causes. It is not always serious, but to be safe you should contact your health care provider right away.
Pelvic exams, blood tests, imaging tests, and other procedures can help your health care provider diagnose the problem. Treatment depends on the cause. Treatments may include medicines, hormones, and surgery.
