CD43, neg blood @ CD36. No AF

I came off bc in Jan. First cycle was 33 days, second cycle 29. Now I am on CD43. I track with OvKit and I peaked at day CD12,13 this cycle. But yet still nothing. I did blood test on CD36 and it was negative. Anyone else in the same boat?? I haven't taken hpt since negative blood bc at that point I figured I'm deff not pregnant. Has anyone had similar experience? How late were you for AF or did you end up getting BFP?
