*warning* TMI sex related... I feel so defeated

The hubby and I were having sex and I got this severe pain in my abdomen. Very hard to describe but if I had to I would say that it was a sharp cramping. We switched positions many times but the pain got worse and eventually to the point where we had to stop. I have a history of GYN problems and have had pain with sex but not like this. The doctor even said once that maybe the pain was cause by the position of my uterus and when I climax be use of the uterine contractions that happenn it causes pain but tonight the pain was the worse I ever felt and I was not having an orgasm. I'm just so fed up with all these problems. I want to be normal. I want to have sex with my husband with no issues. I want to be able to have a child naturally. I want to have a menstrual cycle with moderate pain. I want to be free of random sharp pain. I don't know how much more of this I can take. I just want all of this to go away.
