Having sex hurts my cervix and stomach and back. i'm not pregnant but i am trying. this is worrying me. not sure what could be wrong.

Dysparunea: It could be a variety of things from a urinary tract infection to endometriosis. It could also just be from the penis penetrating deep enough to hit the cervix. A less likely issue would be pid. If you have been trying for more than 6 months to conceive and not have much success, its probably time to see a gynecologist to evaluate both issues.
