Hi there, my suggestion is try and limit iron and fibre intake, if I eat weetabix or shreddies etc... My heartburn is really bad. When not pregnant I have to take 1 mepredec a day while pregnant I need 2 as my heartburn goes through the roof. Milk helps die it down, but if you're getting it bad enough you're throwing up, I would suggest seeing your healthcare provider as it can burn your throat and cause things like larengitis (this happened to me it sucked). Good luck hunni x
If you cant find a natural solution, tums is the only thing that made mine go away and it was Dr recommended.
