Please help

Last night, about 10 minutes after having sex, my lower abdomen started to hurt extremely bad...I think it was my ovaries because I felt the pressure in that exact spot and the pain shot down my vagina. I was doubled over in pain. It felt like an intense cramp that I couldn't massage out or stretch out because stretching and touching the area was too uncomfortable. It finally went away after an hour or so but not completely. I just woke up due to a mild cramp in the same location. Has this happened to anyone?
