Hello fellow TTC-ers!

I need some serious help.... my husband and I have been TTC for 2 years and this month I said let’s try the whole ovulation tracking 9 yards. I have been looking up video after video after video trying to see if ANYONE has had such mixed results... my periods are SUPER irregular (typically between 21-45days). This whole tracking my ovulation is getting even more confusing. Has anyone ever had their line get super super close to positive then disappear twice? I know it can happen once with people who have PCOS and as far as I know I don’t have it. But twice within a few days I’ve had some super close positives or positives and then the next day they practically disappear. I’m so lost as to how I’m supposed to know when I’m ovulating or if I’m going to so my husband and I can get the special positive. If anyone has any advice please help. I’m so lost and I have no idea what more I can do...

For more reference the first test (picture with only 3 tests) and the last test (pictured with the whole list of tests) where taken at the exact same time. Glow showed the first one as positive and the second as an almost positive.
