Cramps cramps cramps death

I have such bad period pains like sometimes vomitting and stuff and I've tried like all the natural stuff and got special painkillers from doctors for it but nothing is helping. I really don't wanna go on the pill (I will if there's nothing else) but is there any other medication a doctor may prescribe because of this? 
Do you think there's possibly a more serious problem since this is every month and lasts like over a week. Although I am very regular if that changes anything idk :/// help mw
