Ok, pretend test results in this post! Changed FF to FAM like Patty suggested and put in 3 higherish temps, 97.75, 97.8 and 97.7. FF still gave me an O date of CD 14.
For funsies I took out my + OPK on CD 14 and it gave me an O date of CD 8 again!!!!

I should mention here that I was using FRER as an OPK which I have never used before and it wasn't absolutely + but was VERY close. I didn't do 2 or 3 a day like I normally do when it's that close because my IC's hadn't come in yet and these cost me $35 for 7 tests!!!

(shhhh don't tell DH!)
Ok, test 2 - when I follow my other pattern of 2 high then 2 drops, without the OPK it gives me an O date of CD 8 again!
BUT add back in my + OPK putting temps at 97.65, 97.45 and 97.35 and I don't get CH's at all! So, I added in one more temp of 97.45 and I get CH's at CD 14!!! Take out that OPK and back to CH's on CD 8 I go!
Seems no matter what I do, I get CH's at CD 14 or CD 8, take out the OPK and it's CD8 which is really NOT believable.
I am so baffled by this chart! Will be interesting how this plays out, and I really wish I had my IC's because now I want to POAS!!!!
