Positive Ovulation?!

Kristin • Been married 8 yrs, actively TTC for 6 yrs. I have PCOS & insulin resistance and never ovulate. My cycles are 100+ days. We just finished our fourth round of clomid.
Easy @ home, round 4 of clomid. Each # is a days worth of testing. Today was day 7. To me it looks as though today's are getting lighter. Do you think any are positive? I've never ovulated before, so if any are positive when would I actually ovulate? Thanks!
