Irregular cycles and LH ovulation test results

Hey everyone, just want to ask advice from anyone who has ever tried using LH ovulation tests.

So I have very irregular cycles ranging from 35 - 73 days (I know) . I've had investigations ongoing for almost 2 years testing for PCOS, thyroid problems, I don't know how many iron tests and hormone profiles and they all come back fine, scans done externally and internally of the ovaries all come back clear, no issues have ever been found but these crazy irregular cycles continue. Summer 2020 I worked really hard and lost 2 stone of my body weight which I have maintained and that really seemed to help regulate me for a while but from the summer just past the problems have started again. I have been ttc baby #3 for well over a year now and I'm very down. So this cycle I started using ovulation tests to see if I could see if I was actually ovulating. I started using them on day 11 of my current cycle and had consistent negatives until day 29 when I had what looked to me like it was a positive result but then the following day I had another positive result. I looked it up and apparently some women do have progressive lh surge and can test positive for couple of days so I was relieved, tested negative for ovulation for the next two days then yesterday the test was positive again on day 33.

Has anyone else ever experienced anything like this?
