Is Glow prediction wrong?

Rachel 👩🏼‍🔬

I swear my Glow prediction for ovulation is wrong.

I am supposed to be ovulating tomorrow, but I have zero cervical mucus and no desire to have sex. Normally, I'm horny as hell and practically dripping with CM (sorry for the TMI) when I'm ovulating. Is it possible that the app is incorrect? Has anyone else had this problem? If so, would you recommend doing ovulation tests? Why or why not?
