Positive OPK and thermal shift on same day?

Hi Ladies, I am a long time lurker with a question. We have been TTC for 3 months, using digital OPKs the entire time. This is the first cycle that I am also temping. I have been very careful to take my temp the same time each morning and the temps have been extremely consistent (around 97.2 everyday). My cycles are regular and are usually between 31-34 days. Last month I got a smiley on CD 18. This cycle, I started testing on CD 14 and got my smiley today, CD 17. However I also noticed a large rise in temperature this morning (up to 97.5). Since my temps have barely varied at all up until this point, the rise in temp seems to indicate my thermal shift which would mean I already ovulated (likely yesterday). However, I did not get a positive OPK reading until today which indicates that ovulation should occur in 12-36 hours. I’m confused by this conflicting information. Any input is much appreciated!!

One high temperature doesn't really tell you much. That is why the monitoring sites don't calculate your ovulation until 3 higher temps. Did you have a rough night sleep last night? Did you drink any alcohol yesterday? There are a few things that could cause one elevated temps.

Also, are you testing twice a day? It is possible that your caught the tail end of your surge instead of the beginning and that could cause you to ovulate the same day as your +OPK.

I suggest to just keep BDing and see what happens with your temps the next few days.

Good luck!

I temped for 2 months and both times I got my and then later FF confirmed that I Oed the same day I got my . I now no longer temp, but I do count the day as the day I Oed. This can make planning a little bit harder, as you will need to before you get your .

Thanks ladies! I have a decent night's sleep but will see what my temp is like tomorrow. Luckily we did BD last night!
