Vfl day of AF…chemical?

AF is due today, I’m about 12/13dpo but I’d expect the line to be a lot darker, am I having another chemical pregnancy?

No sign of AF coming today but equally I don’t feel pregnant.

Desperate for my rainbow baby after a mmc in March. 😢🤞

With my daughter and previous miscarriage, I had super dark lines day of AF but with my chemical they never got any darker than this test.

Thank you for your help x
