Heart burn

Hey ladies I just found out I’m prego (Yay!!!!!) and one of the ways I found out was this terrible heart burn 😫 I have bad heart burn anyway but normally one antacid does the trick, however for the past week I can not seem to get rid of it. It is almost 24/7 even after I take an antacid. I’m gonna call the doctor Monday, but anything you recommend in the mean time? It doesn’t matter what I eat or don’t eat, it’s always there. I am taking Zantac and tums...but they only help a little 😫any help would be appreciated!!!
