I had very bad heart burn throughout pregnancy. Initially, soy milk helped, then I took gaviscon. When that wasn’t good enough, I needed medication from doc. Don’t be worried about baby’s growth though, it won’t affect him.
Maybe can try having some probiotics for your tummy problems. It won’t affect the baby but do eat more often so that your baby can get nutrients too!
I’ve been consuming probiotics even before preg and have up my dosage but does not seem to help
