Did I ovulate

Ch

The first one is the 12th at 5:30pm, the second was 11:00pm on the 12th, Third was 1:00am on the 13th, forth was 6:45am on the 13th (only time I could test before work), the fifth was 11:40pm on the 13th, and the Last one was 2:10pm on the 14th 🤔 so I’m confused as I don’t think it went positive, and now it’s going lighter (I also took one at 11pm last night but it was completely negative. Practically no line for the test line)
