I think I ovulated 2 days after my Peak Day. I finally have a heavy flow today, with the most scanty spotting EVER at P+15 (two instances of 6BG, that I would have missed easily if not checking every 5 minutes), and then PBC AD at P+16. I counted yesterday as CD 2, and started my Femara (I assumed I wouldn't have 3 days of spotting, since my hormone levels were fine.)
But here's the evidence that I may have ovulated later than Peak. First, AF was definitely "late," if going solely by my Peak Day. I just got my hormone levels back from Dr. J, and they were in fact increasing from P+6 to P+8 and even to P+10. Also, my OPKs were + on Peak Day and the day after (then I stopped taking them). Finally, my temps for my thyroid sheet did jump up after day 18, which was P+2. (If I plug in my +OPK dates on Fertility Friend, it does change my O date to CD 18.)
Now, this actually makes me feel a little better. Why? Because now have a good reason why it didn't work last cycle. We selected P-1 and P+1. On P+1, there was no good cm for the little swimmers, so they would have died within hours if there was no egg ready and waiting for them. Then, on P+2 (when I likely O'd), there may have not been many left from 3 days before.
So my plan for this cycle is to use Pre-Seed in the count of 3, just in case something like this happens again. DH also said he wants to go full-speed ahead for 4 days before Peak and 4 days after, lol! Hopefully the Femara will help my CM line up better with my ovulation, though.
This is my last chance at a pregnancy by age 26! And I begin my renewal-Consecration to Mary in mid-July, too... I know Mary will lead me through this next month, no matter what happens.
