Gastric pain during early pregnancy..any remedy/advice?

Hi all; I've been experiencing quite severe gastric pains daily for the last one week; feels burning at the upper abdomen for hours. It happens very randomly; not related to meals. Even when Im eating regular meals; it still occurs. I've tried drinking milk; it helped initially but lately it hasn't been working. I've tried eating round the clock small meals but it still occurs. I'm at a loss. Does anyone have any advice on what I can do? Anything I can take when the attack comes? Thank you in advance
