Can't help you with anything natural unfortunately. #-o

I have had terrible heartburn with all my pregnancies and Mylanta and Gaviscon haven't touched it. Also tried milk, sleeping elevated etc and this didn't help at all.

This time round, I have been prescribed Zantac and this is the only thing that has given me some respite. I suggest that you speak to your doctor/ob for advice.

Hope you get some relief soon.

Best wishes
