8dpo possible implantation?

Kate

I am 8dpo and tonight while having sex I started to spot some pink. It wasn’t a whole lot but it was about the size of my fist of a circle of pink. It stopped after penetration. It wasn’t like dripping out or anything I didn’t even have any on me or him. Went to the bathroom afterwards and wiped and was nothing there really. Mostly CM & the tiniest tiniest amount pink, barely visible and nothing since???? Period isn’t due for 7 more days.
