I’m not sure when I ovulated. Help please

Were any of these tests positive? My app called CD 12 at 9pm positive but it doesn’t look darker to me. Maybe same as,maybe. Then I ran out of tests and had to stop testing. We had family in town so I just didn’t worry about it. Sunday the 21st I got a dollar store ovulation(bottom test) just to make sure surge was over at that point. So I don’t know is if CD 12 was my surge or if it would have been Friday afternoon if I had been able to continue testing. Friday morning is the last test before the dollar store test. What do you all think? I’m just trying to figure out if ovulation was Thursday(positive ovulation Wednesday cd 12) or Friday. Could tests have been that close on Wednesday then not peak till Friday?? Normally my peak is not too long after they get dark like that. Thanks in advance :)
