Implantation bleeding or period?

R.

Hey y’all, so i’m going on 8dpo and having been sore boobs for the past couple days, at this very moment they don’t feel as sore but they are pretty heavy right now. After I wiped yesterday, I noticed a faint red/pink color on the tissue and for the rest of the day...nothing. I honestly haven’t been paying attention to whether or not I’ve been having frequent trips to the bathroom to pee or not, but I just wiped and saw this. PLEASE HELP ME OUT and let me know what this might be
