I developed severe gastritis in my second two pregnancies. So painful that I ended up in hospital on morphine. Had gallbladder tests etc and it was def not that. Nothing (that doctors suggested) worked... but then I changed to a low GI diet and started taking really good quality probiotics to try and address other things and I never had another attack. Well worth a try - even if they don't do the trick for your pain, both can only benefit you and bubs!
