How did you know you DIDN’T ovulate?

I did an opk once a day everyday this cycle. Currently on cd 19 and didn’t get a peak on my digital or strip this month. Strips were getting darker and are now getting lighter. Based on my current symptoms I feel that I’m going into the tww. Usually I get a positive every month. I know I may have just missed the surge but feel paranoid that I did not ovulate this month 😩 which feels terrible because we bd every other day this cycle and I was feeling so hopeful.

If you don’t ovulate every month, how did you know?
