If, however, I change the settings to "Advanced" analysis, which takes all factors into account (I think), I get an ovulation day of CD 17, which puts me at 10DPO today. Considering that I had made a note on CD17 that I had so much EWCM I was doubting my ovulation date, I'm really thinking this may be the correct O date, even though I didn't feel a darn thing. This is the chart with that interpretation. (I also dropped that random high temp, but only because it gave me pretty solid crosshairs vs dotted ones.)
I am suddenly feeling much more optimistic about this cycle. Considering that I apparently started testing at 6DPO (which I thought was 9 at the time), no wonder I've only gotten BFNs.
