Hello everyone It's week 36 now I have heartburn and nausea, I'm running to the bathroom?? Is this normal? Let's say I didn't eat much in the evening so it would be easier I was lying down and then my heartburn started, I went to the bathroom standing but there is nothing to scream ? (Sorry for such detail)
