The most common symptom of endometriosis is pelvic pain, usually at menstruation. Endometriosis can also present as pain at other times during the cycle, such such as at ovulation or during sexual intercourse, or with bowel movements. Other symptoms of endometriosis can be diarrhea or constipation (often at the time of the menstrual period), abdominal bloating, heavy periods, fatigue, and in some cases infertility.
If you have pelvic pain, you may or may not have endometriosis. And women with endometriosis do not always have pelvic pain. In fact, some women with endometriosis have no symptoms at all. It is important for a woman who has persistent pelvic pain to see a physician with specialized experience in endometriosis and pelvic pain.
