Can I get a prescription for pain killers when I'm having my period?

Ok, so I'm almost 23 years old and it seems my periods just keep getting worse the older I get. The first couple days are just unbearable. The second I start, the cramps start. A few years ago I'd have my period... it'd suck and all that, I'd get cramps... but nothing like recently. For the past year I've been getting these cramps that will not stop (literally, non-stop) for, at the very least, 48 complete hours. I will be crying, screaming, and writhing around in pain. I can't get any sleep (neither can my husband 'cause of all the noise I make), and the pain's so intense that it will make me sick (even if I haven't been able to eat all day and have nothing to throw up, so I'll spend hours in the bathroom just dry-heaving, gagging, and choking.)

I've tried Advil, Tylenol, Midol, Pamprin, ibuprofen... nothing helps. I'd overdose on those before I could take enough to relieve the pain. I'm not at all exaggerating. The pain is ridiculous. All I can imagine is that if someone were to stab me in the lower abdomen and twist the blade back and forth repeatedly... well, it couldn't possibly be any more painful than what I'm already experiencing. I'd get my tubes tied to stop having my period... but I want to having children before doing that.

Can a doctor write a prescription for painkillers and maybe nausea medication just for the week that I'm on my period? I mean, obviously, it's the doctor's choice, depending on what he thinks of my situation... but has anyone been able to get a prescription for their period? Or know of anyone who has?

Any help would be greatly appreciated! Thank you! :)
