Implantation bleeding or AF?

My period was due yesterday and sometimes I’ll spot at first but then later than same day I would always have heavy blood where it would completely cover my pad. Since yesterday afternoon I’ve had this type of bleeding/spotting only when I wipe, the bleeding was a little more than this but still a pinkish/brown color when it first started but now there’s less and less every time I go to the bathroom today. There was only one pad that had brown discharge on it but it was a very small amount. Opinions please!!
