What is chronic pelvic pain?

Chronic pelvic pain is abdominal and/or pelvic pain that has lasted for at least 6 months. It might be constant or come and go. The pain does not only occur with menstruation or sex and is not due to a pregnancy.
 
Chronic pelvic pain often starts in adolescence and may have started due to an irregular period. Endometriosis is also a common cause but for some women, there may not be a clear reason it is happening.
