Cramp remedies

I get really bad cramps every cycle. Like hell driven cramps. It's like satan started fighting my uterus and stabbing very hug then set it on fire 100 times over. I go to college so I have to come to class but the cramps really aren't doing it for me right now. I've taken ibuprofen and they didn't help at all. I've tried bananas in the past, lemons, heating pads and electric blankets, nothing.
