Implantation bleeding? 10 dpo

I am 10 dpo right now, AF scheduled to start in 4 days. Temp is still risen. Boobs slightly sore on the sides, i have been peeing a lot, and have mild night sweats the past few nights, but other than that i feel normal.

The only reason i was able to see that this spotting was happening was because i had my finger super high in my vagina trying to feel my cervix.. & when i pulled my finger out (multiple times) to wipe my CM on the toilet paper, out came this lightish pink color.

Usually i only spot 1-2 days before AF and normally it’s a brown color and i always see it after i wipe. Could this be implantation bleeding?
