9dpo weird taste in mouth

Tina

Ok so today I am 9dpo and had a weird taste in my mouth. It seems like it could be metallic it’s just very weird. It literally last all day and no matter what I eat it’s still there. It started yesterday. I have also had very very sore breast (heavy and hurt) from 3 dpo until like today (they don’t bother as much). I caved and tested of course BFN. Anyone else had weird taste in mouth?
