Extreme period cramps

My friends hardly get cramps or when they do they can take a few midol and use a heating pad and pretty much be good, but I get cramps till the point that I throw up. I wake up drenched in sweat and crying because they always hurt so bad. I'm 16 and have had bad cramps for a couple years. I've missed school from it multiple times, no pain medication helps. Does anyone else get them this bad? Or should I get this checked out?
