Positive opk??

I’m really starting to feel discouraged because I think I might’ve interpreted my tests wrong. This is the test that logged a peak positive on my app on the 23rd.

I’ve been bding the whole fertile week and used preseed CD12, CD14, and CD16 believing that I ovulated CD17 so that the sperm had enough time to play catch up. But the as I was testing my surge out on the following two days, the numbers were getting lower but the tests seemed dark

Did I miss my window?? I bd CD18 but didn’t use preseed. The lighting was different for CD 17 test
