Temp Spike but not positive OPK

Emily • Fri, Jul 10

Is it possible for OPKs to miss the lh surge? I've been testing every day 2-3 times a day and my temp spiked to my highest temp this morning. Does this mean I O'd? I'm so sad bc I've been tracking so carefully. I had very little EWCM yesterday then wet now I'm dry. 😭 I did BD every other day this week so far.
