BFN day before or of AF, then BFP?

my cycles are SO routine (29days). I track with OPKs. I O’d late this cycle at cd19 at the latest possible (positive opk on cd17, negative opk on cd 19, and cervix closed and firm on cd20).

im now on cd 34, 15dpo, 1-2 days late on AF (based on my LP from when i O’d, not from my normal 29 cycle length since i know i O’d late).

the weirdest thing is i didnt feel much symptoms this tww, ZERO cramping (which normally i have a few days before af comes atleast). ive been tracking symptoms the past few months and before af im bloated, feeling crampy, fatigued, moody and weird.

this cycle my symptoms have only been vivid dreams, feeling tired earlier at night/going to sleep early, and lately, crying spells (but tbh i attribute that to seeing bfns 😪)

i got a BFN 12dpo with fmu, and a BFN 13dpo evening with a no hold sample that looked pretty concentrated...

im petrified to test again because i dont want to see another BFN and feel like the only way to hold on to hope is to not know, so i can imagine i may get a BFP 😅

can anyone relate? any helpful stories to share?

did anyone else get a bfn 13dpo and go on to get a BFP later?

💕✨love and baby dust for all!
