Implantation bleeding or AF

TMI photos below of cm and spotting!

———-

I am 9dpo and just started the tiniest bit of brown spotting I guess I’d call it. I only noticed a tiny bit when I wiped and the rest when I checked my cm. There are these like brown squiggly lines when I do that.

Is there any chance this is “implantation” spotting or do the little lines mean it’s more likely af

Thank you all so much
