Hi ladies. Something strange happened this month. Usually, my ovulation is very obvious – I’ll get a positive OPK one day followed by a temp shift the next. This month, however, I got a positive OPK the same morning as a temp shift (my temp never rises over 98 unless I ovulate). I figured that maybe I ovulated late the night before (CD16) and was catching the tail end of the surge on CD 17. However, on CD 18 my temp dropped back down slightly again but I was having negative OPKs.
So at first FF gave me crosshairs on CD 16 and said I ovulated then, but today it changed me to CD 18! Very frustrating. What do you ladies think? Thanks in advance!

It’s hard to tell because you have open circles. That can throw it all off.

I’m new to this, but I would say cd 18 because you have 3 high temps above the cover line. I could be wrong, so experts, please chime in!

I’m new to this also, but I agree with CD18. If you had a positive OPK on the 17th then I would think you ovulated after that. Feritility Friend always changes my O date too…its frustrating! But after seeing the big picture and getting a few more days of data it usually appears to be correct.

If you got a positive opk on Cd17, then you even more than likely Oed on cd18…usually you O a day after a positive test….or at least that’s what I’ve read :-/ again, I could be wrong. I just make sure to BD a few days before AND after to cover all bases! However, who am I to talk, because I haven’t gotten KU yet 🙁

Without the OPK I think your crosshairs would have stayed at CD 16. Either way you have some data accuracy problems on your chart that make it impossible to predict exactly when you did ovulate. Your thermometer isn’t precise enough (it needs 1 more decimal point), your missing info on your CM & CP and the open circles indicate irregular waking times. So it’s a tossup for me; CD 16 or 18 for your O.
