Is this OPK positive?

[AnnaCat09]

This is my first time using this brand and its not as clear to me as FR. It seems to be the same shade but not as thick as the other, not sure if that makes a difference, so I need help. This is CD 13 so if this isn't positive tomorrow will definitely be, either way your input is much needed and appreciated!

Thanks for the help!

Thanks! And BTW the control line is closest to the blue.

I'd say you're pretty darn close! If not a full positive I think you're really close to your surge so I would get to it if I were you
