After sex

Soo my husband and I had sex and we did it doggy style and I had my back pushed down and I think he might have hit my uterus or something cause after......holy hell it hurt so bad and still hurts like I was in tears. This has never happened to me so I was wondering if anybody else experienced this b4. The pain was excruciating and almost felt like contractions, but the pain subsided and now it's still crampy.
