Another Twist from FF

I woke up this morning and took my BBT like normal. However the results weren't normal! FF is telling me that I ovulated on Friday (CD27). I don't know if this is because of the fact that I slept in on Saturday, had the time change on Sunday and just an abnormal temp this morning? This is really unexpected and really late, but even if Kev and I missed this round (which we most likely did) I am excited. I work! Yay!
