Could this be positive?

Amber • 30 years old. We have one daughter, born on 2/10/14. TTC #2 since December 2014. Finally pregnant with #2 due 12/4/17!
OPKs here:
The ones with the dots are when I got two seperate digital smiley face peak results from clear blue advanced. I've been using wondflo for back ups and it never got this dark until today. Is this a positive ovulation test strip? Or am I close??? Wondering why two different digital test said I was peak on CD15, today is CD19. Please help!
