Skipping ovulation or false negative?

I’m currently on day 25 in my cycle. I have been taking opks every morning and gotten negatives each time. I usually ovulate around day 14. I’m pretty sure I did ovulate then based on my CM around day 15... but I’m concerned I never got a positive opk.

Has anyone ever had anything like this? How often do opks give false negatives? I use the clear blue digital opk tests.
