*UPDATE* *color got lighter pink than original pic, never turned into a flow and has completely stopped. Nothing on toilet paper when I wipe now*Is this implantation? Or my period?

I am supposed to start my period today. I always have my

Period as son as I wake up and go to the bathroom the day it is supposed to start without fail. This morning I woke up, went to pee, and nothing was there. Nothing all day until 15 minutes ago. I went to the bathroom to see if I had started yet, it was 3 pm and I’m never this late in the day for my Period to show. I went to the bathroom, not a drop in my underwear but this on my toilet paper when I wiped. Is this implantation bleeding or my period? It hasn’t gotten heavier at all. Please help!
