Breast soreness despite starting to spot


So I posted a few days ago about having sore side of my breasts/under armpit area.. I am CD 12/13 today and last night I started to spot very small amounts so I’m thinking AF is here..

This was my fist month getting sore breasts aside from my chemical last month.. but I read many girls’ sore breasts stop with AF..

Did any get a BFP after a situation like this or should I count myself out, BFN today on FRER! And again my breasts are still equally or more sore than yesterday! Any response appreciated!
