AF late, but BFN and BBT dropping- help and thoughts?!

[Hopefulhoney6]

I always have a 10 day luteal phase, so should have got AF on Sunday 29th (11DPO). Confirmed ov with BBT and OPKs.

Im now 13DPO and no sign of AF. BFN on a FRER on 12DPO. Haven’t tested again.

BBT dropping (but not yet right down - see picture).

I had a MMC in December & have had one AF since, so maybe my body is just getting back to normal?! And I’ve also started acupuncture so maybe this affected it. Any thoughts??

any chance I could still get a BFP if I test tomorrow at 14DPO. Or would a FRER have picked up at 12DPO?!

Just in case anyone ever comes across this, I know no one replied but it turned out the reason I wasn’t bleeding was Ashermans Syndrome - scarring caused by the D&C for MMC. So if anyone is ever in the same boat and is worried, especially if tracking BBT. It’s worth researching!
