Really bad heart burn! 😖

Mercy • I'm 27 years old and me and my husband are expecting our 2nd baby in March. Our daughter is almost 2 and we are excited to be giving her a sibling!
I have acid reflux disease and stopped taking nexium once I got my BFP but this heartburn is killing me! I try to stay away from things that make it flare up but it's really hard with such a low appetite. Has anyone been prescribed something for heart burn while pregnant? I'm 7 weeks 3days. Thanks for the feed backÂ
