Chart stalk me - O day?

[belle55]

So FF is saying I O'd on CD 18 (I had a positive OPK that day). But my temps didn't really spike until two days later. So is it for sure CD 18 or is there a chance it was CD 20 instead? 

It's just kind of odd to me since typically I see my temp spike the day after my positive OPK. Am I understanding things incorrectly?

I haven't looked at charts in a long time (I was slightly obsessed when TTC my first 4 years ago) but I'd say from the OPK and temps it looks like CD20 for O, unless that temp is a fluke for some reason, then maybe CD19. Good luck!

If you take out the ewcm on cd 16 does that move it?

What happens if you remove the temp for cd19?

I would say it's most likely that you O-d on CD20. A positive OPK doesn't necessary mean that you are ovulating right.that.second. It means that you will likely ovulate within 48 hours so that puts CD20 squarely in the timeframe.

I think when you have a + OPK, you're supposed to O within 24-48 hs, so I don't think you Oed on the 18th. I think CD20 seems more likely.

Good luck!

I tried taking out the temp on CD 19 and the EWCM on CD 16 and FF did not move my crosshairs. It must go off of the positive OPK more than the other indicators? Either way, I'm leaning toward O on CD 20 since that makes more sense to me. I guess we'll see when AF shows up.

I would say CD20 based on thr+ OPK on CD18.
