Did I ovulate?

My app said I was due to ovulate around Sunday just gone.....So I started doing opks from last Thursday, which was faint, then Friday it got a bit darker, then Saturday morning a bit darker still, and then I never did another till Sunday early afternoon which is the darkest one in the pic below, But then by Sunday night it was a bit lighter (the other pic below)....., and then theyv been getting fainter ever since. Does this mean i missed my peak and had a short surge?? Or did I not ovulate? I had watery discharge over the weekend but last night it went white and creamy . Please reply I’m so confused as usually I ovulate regularly
