HELP!!

My boyfriend and I were having sex same as usual, but I had to have him stop because my stomach started hurting. It got worse and worse and I felt like puking. It felt like I was being sliced open with a serrated knife. I started getting anxiety and couldn't breathe. It hurt to move(still does). I took off my dress and bra and threw on some of his pajamas and that helped. I went to the bathroom and that helped a little too. Now I'm curled up on the couch trying not to move. What could have caused this? I had testing done last week and was told yesterday I am infertile. I ate quite a bit within two hours before sex. Help???
