okay so in the last year and 1/2 i have gotten a horrable pain while havaing sex. Never have i had this problem befor untill I got chlamidia from my cheating boyfriend. I have been to the doctor multiple times and everytime all the tests are neg. and they say im fine. It also sometimes hurts with out having sex. Its a horrid pain to the point of my not wanting to have sex at all. I went to the doc again recently and once again they say im fine but this time i was able to get the doc to okay an ultrasound. Anyone have any ideas of what this could be from?
