I've become a crazy line reader

Carrie

I'm 9dpo. Af should arrive 12/24 so I'm 4 days out. I've never tested this early, but I went on a whim today. I swear when I stare I see the faintest line ever. I don't know what an indent looks like, but I guess it could be that.

My question: has anyone ever tested this early and seen the worlds faintest line only for it to become a bfp later? If so how many days?

Thoughts anyone?!!!!
