Help 12dpo

So I’m 12dpo, period is due in 2 days (Friday). I’m experiencing pain prick cramps, lightening Crotch, sore breasts, nausea, backache and headache.

I wiped earlier and there was light pink blood when I wiped. I put down toilet paper in my underwear and haven’t had anything since. I have even used the bathroom twice since and nothing. I did have some discharge though that was creamy and white. I’ve had that for the entire TWW.

Could this be implantation bleeding or do you think AF is just early?
