Af or implantation? Tmi!

Kaitlyn • Engaged& trying for a year now!❤️ baby dust to all
On Monday (8dpo) after bd we noticed blood on him and we figured I started af, it was bright red because it was also mixed with semen, I noticed a little bit of blood through out the night and no clotting, yesterday and today cm is creamy and kind of heavy. Af is supposed to show on the 25 (I have a 41 day cycle) and o was not confirmed. I'm a little confused, has anyone else experienced this?
