I am pretty good at tracking, and usually test 12 DPO and if I do not know when I O'd - then I test 2 days before AF is due. Well looking at the calendar, this time 12 DPO = AF? So now what? AF is never 2 days late, so what does this mean? And would you test before AF (10-11 DPO?).
Sounds to me you'll have to test the day AF is supposed to come for the best accuracy. I'm sure you can POAS a day or two earlier, but it might still be too early.
Hope you get your BFP++++++++++++++++++++++++++++++++++++++++++++++++
I have the opposite, I am 7DPO today, which means that by next Friday I will be 14DPO, but I don't expect AF til Sunday! Ughhhhhhhhhh hope she gets LOST!!!! LOL
