Idk if I’m ovulating!???

Okay, so back story I had a miscarriage in October. I have been tracking ovulation since and have gotten positives but no pregnancy. This month I have gotten darker lines on my tests but no confirmed positive. Today I thought this morning looked pretty dark but still wasn’t darker than the control line. Now I just took one 10 hours later and the line is barely even there. What does this mean?! Did I not ovulate? How can I but Italy make myself ovulate if not?
