why does my stomach hurt?
since you say you've pooped, its probably a stomach bug.  make sure you drink lots of liquids water/tea, not soda or beer, and eat non fatty food, like toast or pasta.  if the symptoms continue for a while...go see a doctor.  \nif you vomit repeatedly over the time of a cpl of hrs...go see a doctor.  \nbut im not a doctor...so you're best bet would probably be to call your doctor or emergency room, describe your symptoms, and they'll let you know if/when you should come in.
