HORRIBLE GAS PAIN/LOWER STOMACH PAIN DURING PERIOD?

so my pains woke me up at like 6 this morning. the day i get my period i have HORRRIBLE stomach pains it almost feels like REALLY bad gas pains [without farting] or like those stomach pains you get when you have diarreah. it's bad. i took two midol one aleve and two gas x's. i don't know if its gas but sometimes when i take gas x it gets a little better. does anyone know whyyy this happens or if it's gas or something else? anyone know anything i can take to make it go away? the pain gets REALLY REALLY severe to the point where im crying and rolling around and then subsides for a minute or so and then throbs back and yeah. ):
