OPK help

I usually ovulate around CD 17-18 according to my OPKs, but I’m wondering if I might have possibly gotten my peak on CD 14 if I had tested in the evening. Usually my strips get gradually darker until my peak, but they’re staying the same/getting lighter. Do you think I could have gone from the .55 in the morning to a positive if I had tested in the evening?

Regular 30 day cycles, currently morning of CD 17, super negative opk.
