I don't know if that's how you properly link your chart or not?
I wasn't a fan of using FF and don't agree with its dashed crosshairs (what do dashed crosshairs mean?).
This cycle broke a lot of rules, which is part of the reason I'm feeling so weird about things now. I'll try to include the notes in my chart so you can see when all these things happened. I was crazy sick when my temp'ing should have started, so I missed a good chunk of time, started back with a new thermometre, and O'ed earlier than in my last 2 cycles (infact, probably earlier than I've ever O'ed). We broke the 6:00 rule and DTD one morning only to see stretchy CF later that day (and it then turned to EWCM the next).
I only have 2 legit pre-O temps (CD16 and 17) the rest I fudged in hopes of FF moving my crosshairs closer to where I'm fairly certain O occured- CD 18, but they're reflective of my normal pre-O temps (35.9 degrees to 36.15 range). My CF dry-up and cervical position both point to CD 18 as well (didn't enter all that into FF yet).
So, I disagree with FF's crosshairs and believe I O'ed on CD 18 (CD 19 is my norm, though for the last couple cycles it's been CD 34 and 50).
Sorry, that's a lot of random info. I'm going to mess around with FF more. Please let me know if that link works properly for you.
ETA: I was re-entering data and discovered FF moved my crosshairs because I was missing a temp on or after the day of O (I have a low temp CD 17, didn't temp CD18, then a high temp CD 19). I entered a second low temp there just to say that if I did O there it would be later rather than earlier. So now, FF agrees that I O'ed earlier (except it says CD 17).
Man, I made a good mess of this one!
