I wouldn't start discarding and altering temps to try and change your ovulation day or to make your chart look better. Even if you discard CD11, you still haven't had a clear and "sustained" thermal shift until CD18. Sorry I am still going for CD18, didn't you say you bd around that time just in case?

Are you a VIP member of FF? Why not ask one of the mods to check out your chart, just for piece of mind.
