Brown spotting - Implantation or AF??? 🤔🤔🤔

Me 👼🏻 7/26/19; 👧🏽 6/1/20

Started getting a little brown spotting on 2/2 only on the TP when wiping. It’s very minimal. Today is day 3 of this happening. AF is expected 2/9. I’ve spotted brown the morning of starting AF a few times in my life, but never days before, for several days, or this minimal.

Crossing my fingers it’s a good sign for a possible 👶🏽 ???

Could this be implantation?? Or just AF coming?? Has this happened to anyone before a BFP??
