Implantation bleeding? Tmi pic

I'm 8 dpo, 7 until my next AF. I'm trying to watch myself for symptom checking and getting overly excited but yesterday I started having light pink bleeding. I dismissed it as possibly irritation from bd but then today it is more rust/brown. My AF is consistently red and much heavier so I'm at a loss. Can some ladies with more experience help out? My annual is Friday so I'll know for sure then!!!​
