TMI Is 12 DPO too late for implantation bleeding?

I’m 12 DPO today and was ready to give up hope (period is due in 2 days) when I noticed this when I wiped. Last month my period came 2 days early and started with light pink blood but much more than this and it made me think it was implantation..then AF showed up later that day. With my 1st pregnancy I never noticed any implantation bleeding.

Has anyone ever implanted this late and got a BFP days later?

Thanks
