Tummy cramps since last night?

Hi, I have been having bowel cramps since late last night, and only felt it after drinking Powerade(is it the citric acid?)and today I am just really gassy and have had several bowel movements, stools are rather similar to when someone eats a lot of fiber, sometimes stifling( I'm sorry I don't mean to sound gross), hesitating, gut churning, but not too much. Could it be hormones? I just got over the second phase(applies to women)about a week ago. I ran last night and got really overheated, and prior to that I ate dry granola. I also ate granola and drank Powerade after that.
