Can someone please just sum up what having heartburn feels like, I know it's common in pregnant women so I knew it would come I just never knew how it would feel, I want to make sure this is really heartburn that I'm feeling and not anything serious bc this feeling truly *****, its feels like my throat and chest are just collapsing (that's a bit dramatic) but it really is an uneasy feeling, my throat is very irritated, my whole inside just feels really gasy...
