Ok, coupla questions, because this chart confuses the dickens out of me, and even though I chart on paper and do not rely on FF-- only use it for sharing charts-- FF changed my ovulation date TWICE. I'm fairly sure I ovulated on day 17, because day 17 or 18 is pretty normal for me, and matches up nicely with the last few months. TCOYF rules for slow-rise or stairstepping would let me confirm a coverline at 97.6, and ovulation on CD17.
HOWEVER... FF had it pegged at CD20 for a while, and that does match up better with the CF signs. Also, a CD20 ovulation would give me a more normal (for me) luteal phase of 11 days (longest I've ever recorded was 12 days, last month). On the other hand, I really want ovulation to be CD17, because that would give me my first-ever full-length 14-day luteal phase (yipee!). Also, we had sex without a barrier on the morning of CD22, and I don't want to think I'm that stupid... though it did break the peak day rule. Ngh. Also, if I ovulated CD 20, then I dropped onto and under my coverline on CD26 and 27 without starting my period, which would be very, very weird.
Since I've already started spotting, I'm not too worried about being pregnant. But I really would like to know how long a luteal phase to record here. 14 days would be really exciting.
