tricky chart - any ideas what is going on?

[jenmegc]

Hi all,

I tend to be a pretty regular ovulator, usually day 18-19. This month I'm on day 23, with not a temp spike to be seen. Any ideas what is going on? (besides ovaries that can't make up their mind)  

Thanks!!

Well, FF is guessing that you O'd on CD 21, but it's uncertain (hence the dashed crosshairs).  I'm uncertain as well.  It's possible... it's hard to tell b/c of your erratic pre-O temps.  FF likes the temp dip along with the fertile CF on CD 21.  But your fertile CF continued and your temp didn't actually surpass your pre-O temps until after that.  So I am more inclined to say you O'd around CD 24.  What was your CF like on CD's 24 and 25?  If it was fertile on CD 24 and drier on CD 25 I'd say count from CD 24.
