Implantation bleeding?

I’m 12 dpo and af is due in 2 days. This morning I had some spotting only when I wiped.. I put a pad on and thought af was coming early.. I checked my pad and nothing is on it and again just when I wiped very little spotting and it’s less than the first time.. is it possible?? I thought I was out since I haven’t got a faint line yet!

This morning
