FF is messing with me at the worst time! This mornings temp put my O day at CD 10 instead of CD 20, so its put me at 20 dpo instead of 10! Already struggling to hold off from testing too early, and the fact my temps seem to be increasing even though AF is due tomorrow is making me get my hopes up... my temps are normally erratic before O and seem to stabalise after O, so does anyone else agree that my O day is CD20?
