HELP!

i started my period yesterday, around 5-6 P.M. i had horrible cramps but i didnt take anything to help them.. by the time i went to bed ( 11:40-12:00) my cramps were no where near as bad.. but in my sleep i started to toss & turn due to a sever pain in my hip. it feels as if the gassy cramps from my lower abdomen have found there way into my left hip.. any body else have this problem & know how to help??? i woke up screaming crying & cant seem to figure out how to get it to stop.
