Endometriosis?: If this pain only happens during your period, it may be endometriosis. This is a condition where endometrium, the material lining the inside of the uterus, grows outside the uterus. It typically causes pain associated with your monthly cycle, as you are describing. See your ob/gyn for and evaluation and more information.

Endometriosis?: It is possible there is some scar tissue or endometriosis causing a problem. It also may be GI related. If it persists it is definitely worth getting checked out to make sure there is nothing to worry about. You might start first by seeing you gyn.
