Trying to Get Pregnant

Do you think FF is wrong?

This cycle has been really wonky for me. Between switching thermometers mid-cycle (yeah, I know - long story) and missing a few temps, my chart has been kind of all over the place. Per your suggestions yesterday, I discarded the temps I took with the old thermometer, and this morning FF gave me crosshairs - yay!

However, FF is putting my O date as Saturday, but I got a positive OPK on Sunday. Don't you think it's more likely that I ovulated later Sunday? Monday would seem even more likely, based on OPK, but my temp had already risen by then. Unfortunately I missed Sunday's temp (out of town, forgot my thermometer), which turned out to be a critical day! Argh. If I put a low dummy temp in for Sunday, it shifts my O date to Sunday.

Does FF even take OPKs into account when calculating your O date, or is that just one of the data points that's for your own information?

So let's hear it - based on my chart, when do YOU think it looks like I ovulated? Or should I trust FF?

(edited for clarity)

  • I've had +opks the day after O. Since there is no opk for Sat and no temp for Sunday, I'd stick with Saturday but remember at the end of your LP that it could have been Sunday. Dummy temps don't help or show anything.

    Ah - good to know, I hadn't realized that you could get a + the day after O. Makes more sense now why FF would put my CH's where it did. Sigh. Hoping it really was Sunday, though, as the BD timing would have been MUCH better. :/

  • your CH's are dotted.   Meaning FF really doesn't know.

    you are missing Sunday's temp.   If that temp had been low, I bet your CH's would have been on Sunday.  If Sunday would have been high, O would be on Saturday.

    So it all depends on what that Sunday temp might have been.    This is why I used to hate when I'd miss a temp around O.
