ARE ANY OF THESE POSITIVE? PLEASE HELP

Glow is telling me that today is the highest chance of pregnancy and that tomorrow is my ovulation day. I would really appreciate if someone could tell me if any of these are positive?! Ive had VERY strong opks before that actually lasted like 2 days long and these dont look as strong. The one marked "2nd urine" was taken about 20 minutes ago. Im on CD20 today. What do you ladies think? TIA
