Another month another letdown

1 day late today. Had some pinkish discharge when I wiped today but no sign of af. There's no denying however, this test is a bfn. I had bacterial vaginosis & started medication to treat it right after I ovulated, I'm hoping if this isn't my month that is the reason why. This will be our rainbow baby after losing ours at 16 weeks to a battle with a subchorionic hematoma, terrified I could have developed ashermans syndrome due to d&c to remove retained placenta. Also to top it all off I have a "niche" on my csection scar😒so discouraging
