Hi I am the same, right from the start I had really severe acid reflux and indigestion. Now 11 weeks and it has eased a little . I have been put on medication for the acid reflux because it was so painful I just couldn't eat. I have also put myself on a gluten free diet and noticed that my digestion has improved. Not an easy time at all!!!!
Im 12 weeks 3 days and omg iv been suffering with this issue badly I have cut out all dairy products and it has helped a lil I think keeping a food diary is good somtimes you can gain a intolerance to certain foods while pregnant hope it gets better ;)
I am 5 weeks +4 and I have been having digestion issues as well. I think mine has been cause by my suddenly erratic eating habits.
