Pregnant???

Okay so as of today I’m currently 12 days late and 26 DPO. I’ve never in my life been more than 2 or 3 days late. I haven’t had any spotting or anything until today. (Possible TMI coming.) I felt something wet that felt like period blood so I checked and it was very light and brownish. There was a pink tint to it but there wasn’t much there. When I went to the restroom nothing came out like it does with AF. There was brown and pinkish “blood” (I guess??) on the toilet paper when I wiped though. It wasn’t very much, kinda the same amount you would have the very last day of AF when there’s nothing really left just the last little bit (if that makes sense). Could this be implantation bleeding? Or is it my period? Or something else? I’m just very confused, any advice would be very helpful, thank you!
