question: Ive been feeling really sick and i thought it was the stomach flu but my body has not done anything to get rid of it, no throwing  up or diarreha. Sometimes its just nausea, then gas, and then a sharp pain and it various from above my belly button to my lower abdomin. I havent noticed if its on my right side, though it seems to be in the middle. Also my period is delayed and we have been trying for a baby but i tested neg on the home preg test. is this just  the flu or would it be appendicitis?
