Lately my stomach has been messing up, Like I'll feel hungry, and then I'll eat very little, and then I'll feel full and have period like cramps and feel nauseous, and then I'll feel hungry again, and I burp non stop. I can wake up and sit up, and I'll have to burp. I think I have acid reflux, but I never have heart burn. Idk what to do, I've been to my dr too and nothing.
