I'm currently 5 days late. Still no sign of af. I got very faint lines all week, yesterday got a very faint but obvious line, and now I'm getting bfns. I'm convinced it's a chemical pregnancy because my lines should be getting darker. And af has still not shown up. No spotting. Not brown or red discharge at all. Not really sure what to do. This will be my 2nd chemical pregnancy after a mc in may 2019.
