AF being weird or possible implantation bleeding?

Don’t have a photo to show since I was super confused. But wiped and there was super light pink fluid on the toilet paper. Wiped again and nothing. That was around 8 hours ago.

Just now, wiped, and a small, thin amount of brown discharge. Wiped again, and nothing.

I would be around 12DPO today, AF is due on Saturday. Was just gunna wait it out but definitely caught me by surprise.
