Did I ovulate early?

This is my first time using OPKs so I’m not sure if I’m missing something here.. on CD9 I started using OPKs for the first time, and thought I’d just use one every morning until my results started getting stronger. I know that the test line has to be darker or the same colour as the control line to be positive, so when I tested 3 days ago and I had a faint line I thought ‘maybe it’ll be positive in a few days’.

So yesterday morning I tested again, and the test line was fainter than the day before and then just now, I’ve tested and it is even more faint? Did I miss my peak or is this normal leading up to ovulation?

All opinions will be appreciated! Thank you!
