Accidentally swallow some chewing gum, now have pains in stomach ?

I was on the bus on the was home chewing some gum when we went over a bump and I accidentally swallowed my chewing gum. Now I have sharp pains in my stomach 12 hours later, which is forbidding me from sleeping. I really don't know what to do. And to make matters worse, it's my prom tomorrow. So I'm panicking over how to get rid of the pain before then.
