DOH!!!!!! 
If you're still awake now, put a hot water bottle or a heatpack
over your abdomen. Prop your legs up on a pillow or
something.
If the pain persists, see a doctor so he can prescribe you some
medicine to curb those pains.
If you always get cramps during your periods, see a doctor
immediately. The pains could be a bad sign. If you sometimes get
cramps, try taking EPO daily. Or cornflakes help, for some.
