I get really bad stomach aches everyday, (usually in the morning or at night.) I'm not sure what it could be, but I am very worried. Sometimes the pain is high and sometimes it's low, it also sometimes comes with nausea. My mom said it could be because of my diet. I have been binging quite often, but I've been maintaining my weight, so I didn't think that was a problem.
I haven't had my period yet, so is that what it could be?
I had a mild back ache earlier today if that's any help.

Thanks in advance
