Pregnancy acid reflux or stomach problem

Anyone feel uneasy everyday on your stomach? Not sure if is acid reflux or bloated. Just keep burping after eating. Passing of stool also very smelly. Sorry I'm just comparing as before pregnancy i do not have this problem. Really wonder what shld I eat everyday to make my stomach reflux or air better. I already do not eat a lot. Eat 70% full only. How you all handle anyone same as me? Is like very hopeless feeling. Very upset.
