m 15 years old and I eat decently healthy and get moderate exercise, like walking around school all day,
orchestra, and running sometimes as well as gym class and stretching almost every day. I'm very concerned about this and I weigh around 86 pounds. I am a skinny person so it very clear that my stomach is a little larger. I don't have a clue what it could be and there is no way that it's possible I could be pregnant or anything like that.
