How can I make my stomachaches go away?

okay, soo...its 2:45, and i have to wake up in 6 hours for softball practice :/ the thing is, i cant fall asleep. i just got my period like 5 hours ago, and my stomachache just wont go away. im laying in bed, feeling like ****. are there any simple ways to make them go away in the next half hour? i tried aspirin, hot water bottles (ik thats mostly for cramps, but i was desperate), and moving around...that usually helps or works all the way for a while...and they say it helps with cramps or if ur stomach hurts (while on ur period, i think). nothings working, do u guys have any simple household ways to make em go away? lol im really desperate and feel terrible...im tossing & turning and i feel like im gonna cry...thanks :|
