Does AF come when she's supposed to after a chemical pregnancy ?

H

AF due February 2nd.

Pregnant all week, miscarried February 7th.

Would have ovulated on the 14th originally.

I'm 28-29 day cycle. So AF should've been due March 2. Still nothing. While I THINK I saw a line on my tests, they aren't dark enough to convince me. What do you think?
