DPO vs Cycle Day?

Marcie
Sssoooooo .... General question for y'all. Does anyone know which is "more impotant" when judging whether or not you should probably have seen a BFP by now? DPO ... or Cycle Day/AF is late? ... AF was due today, didn't show :) temps have remained slightly elevated since Ov Spike. Still BFN. .... I'm an early ovulator though and I'm 17DPO .... i would see BFP by now, right?
