Hi Bleux, your two O days must have been sooo confusing especially with the CM signs!!!!
I did my test run and am not happy with the result! i did BSF 1 1/2 hour before testing ph, EW 1 hour beofre and big O 1/2 hour before and this is the result....
i would say between 8 and 9, would you agree? i may just insert 10 minutes before this month and if i dont get BFP will put in earlier next month.
