Menstrual Cramps

Okay so my period is due any day now and I get scared every time it comes around because my cramps are so severe I can't even move I have to lay down immediately and no medication has worked I tried everything from off brand or Aleve, advil,Motrin, midol, ibuprofen etc... So what do I do next? My doctor gave me a prescription and it didn't do a thing. Do I just suffer?
