Postpartum indigestion???

Mel

I’m 4 1/2 months postpartum and am still dealing with bad indigestion each morning. I can’t eat anything after dinner and even if I eat a larger dinner hours before bed, I wake up feeling so sick. This started happening late into my second trimester and stuck throughout pregnancy, but i assumed it was from baby taking up so much room. Has anyone else had this issue postpartum? It’s so annoying and happens daily.
