Did I ovulate?

Hey ladies. This is my first month off the pill. Stopped the pill at the end if the pack, had my withdrawal bleed, and then started ovulation testing. I usually test once every 2 days. I'll insert a photo of my line progression. I'm confused because I have yet to get a true positive. It went from so faint to suddenly quite dark (but still not positive) and then back to faint. The test I took yesterday was the darkest yet I've seen. So my hubbs and I got busy last night lol. I took a test today at 12pm because I was curious and it was about the same, maybe a bit lighter. I then took one today at 5pm and it's almost not there. Do you think maybe I ovulated sometime last night? Or maybe I did something wrong? Maybe I shouldn't have drank water so the urine would be less diluted at 5pm? But I really didn't drink much today. I dont know what's going on. (All photos were taken in valid time frame.)

Above is my test from yesterday 5pm.
