Bleeding Between Menstrual Periods

Other causes of abnormal bleeding include an ovarian cyst, vaginal irritation or infection, a fibroid or polyp (benign growths) in your uterus, a polyp on your cervix or another cervix abnormality (rarely, including cervical cancer), or a menstrual pain problem named endometriosis. It also may be from a failure to ovulate during this cycle (failure to release an egg from the ovary), causing what is known as "dysfunctional uterine bleeding."

Your health care provider can evaluate these possibilities during your office visit.
