Helping PMS pain?

My friend has really bad PMS stomach pains the first day of her cycle, and I feel bad for her because she can’t get birth control pills to help with her pains.
I’m wondering if anyone here has any suggestions I can give her to help with the pain on the days she can’t just lay in bed and sleep it off.
Asperin doesn’t help, ether. It seems that just being in pain is her only option, and because I’m a dude, I have no idea what it’s like or how to help. I just feel so bad for her.
