I agree with Trudie. You need to see a gynecologist and have them do the transvaginal ultrasound and take a look. Something is going on, could be cysts, could be endometriosis. Let us know!
I'm so sorry you are hurting. It does sound like a cyst problem but could be something else. You need to get the cyst issue ruled out. Insist that your doctor do a transvaginal ultrasound to take a look and then force the follow up. On the health pages (top right) is a posting on types of cysts and symptoms that you might want to take a look at it. Good luck and please keep us posted.
