Help needed

I’m on CD 20, usually ovulating on CD24.

According to glow I’m on the 3rd day of my fertile window (I know it’s just an app but kinda makes sense).

I have watery cm but all my opk since two days ago are completely negative. Not even a super faint line. Nothing.

Usually by now it starts getting darker.

Did it happen to anyone?

We’re BD every other day but I just don’t feel like ovulation is coming 🙈
