Late Implantation bleeding = late positive?

I think I saw implantation bleeding (light pink mucus- only two wipes) on Monday at noon. That was 11dpo for me. I haven’t seen any blood or anything pink since then. I’m now 14dpo and only getting negatives. Period was due yesterday and it didn’t show, but wondering if I really could see a positive later on. 15 dpo or more. Any insight? It should be positive by now, right?
