    I think it did this because OPK strips detect the LH surge that comes before ovualtion. You typically ovulate 24-36 hours after your LH surge.


    P.S. Your chart for this month looks similar to mine at least after ovulation.

    You are fine! OPK detect your surge before actual O, this is confirmed with your temp rising, so FF moving your CH totally makes sence.  FX

    @hoogirl05:  It has happened to me. I think what FF is trying to do is adjust according to your positive OPKs. Last cycle I had two + OPK in a row like you and FF changed my O day to the day of my second +OPK. This cycle I only got one +OPK and like other bees have mentioned, it confuses FF to have more than one. In my understanding, I would say you O’d during or after your second + OPK. I think FF is right on in selecting day 17. Good luck!

    I am glad I am not the only one who always questions my ch!  I have started to think I need to learn to trust FF.  I know that OPK are supposed to detect your surge before ovulation, but FF put my CH on the day of ovulation, so I don’t know what it is doing!

    @onyx81:  I need to learn to trust FF too!  It always correctly predicts my O date even when I’m suspicious!
