Stomach aches everyday. Not on period. Excessive bloating. 14 years old.

I am 14 years old, and have never been sexually active.

for the past three weeks, i have been having stomach aches every day, some times more than once.

i am not on my period, but this has been happening for a while--no matter what i eat, i bloat. i can gain up to three inches after a meal around my waist, even if it is only a bowl of cereal. the bloating has been happening for as long as i can remember, even when i lower sodium intake and monitor water consumption, but the stomach aches are a new problem.

i eat very healthily, and have a high fruit intake.
