Is this positive?

Pic taken right at 5 min. Thought I had ovulated 2 days ago (Sun) because I got what I thought to be a positive Sat as well as had been cramping all weekend (that's what prompted me to check an opk) . Today is CD 12 for me and normally I have been ovulating Day 15-21, so I'm early this month. I checked Sun & Mon twice a day and noticed the lines started to fade a little but now this looks the darkest it's been....BD'd once 3 nights ago (Saturday).
