Heartburn Disease I Have The Worst Heartburn, And Acid Reflux Disease...?

I have the worst heartburn, and acid reflux disease...? - heartburn disease

I am 18 weeks pregnant and have the worst heartburn. Nothing ever worked. Even if I drink water, and when burping up acid in foods when I eat something. I can not bear it! What can I eat to help, Tums will not help me.
