I always use ibuprofen. I get pretty bad cramps around my 'time', and I find that it helps a lot. Motrin contains ibuprofen. Tylenol is also a pretty good painkiller, too. Both work well for headaches and cramps, I've found.
If 你 don't take painkillers, than there are some other options, too. Heat is very good for cramps-- a heating pad 或者 a warm bath does wonders. When 你 are on your period, (and you've probably heard this a million times), try to stay away from salty foods. It sounds crazy, but not eating them really does help. :)
你 can also get homeopathic remedies which are of course natural they take a couple of months to start working but I know from experience they reduce the problem not necessarily completely but to a point 你 can live with. So ask a Homeopath.
你 can take ibuprofen 或者 midol, but I dont like to because i heard it makes your period last longer. I just heat up one of those heating pad things (technical term for it) & just lay it across your lower stomach, 或者 eat some bananas & chocolate. Thats what works for me.
Ahhh, I think people have done it already. XD But Ibuprofen is certainly the best medication for period pain; only have to wait a couple 分钟 and it's gone, just like that.
Though a really nice touch is to put a warm to hot damp washcloth on your lower stomach, above the lady parts. It can really help soothe. And I heard 浓情巧克力 can help too. XD
Stay away from caffeine! It supposedly makes 你 feel worse.
