OPK help

I just took one on a whim and I know that's not proper testing as it is best to test 3xs a day. I'm pretty sure I already ovulated as my fertile period is over and my cm is changing back to cloudy and sticky. I was more or less wondering if this is how it looks as the LH hormone starts to decrease again. This is my second cycle off bc. Prior cycles to bc were about 34 days and first natural cycle after stopping was 45!!! So far I am on cycle day 26. Thanks for the help
