Yep, that works. I'd say FF has got it right because you stil had EWCM on the day of ovulation - if you had ovulated earlier the EWCM should have dried up. You are still in with a chance if you BDd in the week before.
BBT charting is so inexact and hard to interpret - why don't you try OPK next month too if you don't get your BFP so you can get another way to confirm when you ovulated?
Good luck!
