pain!

Okay so I was getting ready for bed just now, laying down, not doing anything and out of no where I got cramp like pains in my lower abdomen/pelvic area. I thought it was just cramps but it's just one huge cramp pain that hurts so bad!!! Has anyone ever experianced this? I'm honestly not sure what it can be. No other symptoms or anything just this random pain :/ (had biopsy done on cervix two weeks ago, could it have something to do with that?)
