Opk help

Ta

So we been ttc for a while now and I been using opks to help but I have very gotten a positive one. My blood work says I ovulate so I just thought I keep missing it. My period ended 2 days ago so I thought I’ll start earlier and I got line that seems darker then it should be at this time of the month. The app says I’m two shades away from a positive test. Could I really ovulate this early??

The pic doesn’t show just how dark it was. It’s not positive but I get test that don’t even have a faint line so it’s blowing my mind.
