So confused

[spicyorange]

Stopped mini pill 30 days ago. Bfn 2 days ago. No af since I stopped. Yesterday a tiny red streak in my cm, same again today but no af. Totally confused. Cycle used to be a nice neat 29 days but then the pill had thrown everything out. How do you know implantation vs af vs something else

I should add that going by my cm cycle plus time I should have af already but it's not seemingly like it's coming
