Weird taste in my mouth...

BB

After EVERYTHING I eat. It could literally be a breath mint and my mouth taste gross immediately after! I mean, I was obsessive about brushing my tongue after each meal, but now it feels like everything I put in my mouth causes me to have this feeling (everything besides water, but even liquids are doing this to me now).

Never happened before pregnancy, does anyone know what this is/what’s causing it/ how to prevent it?
