Opk question!

On the pregmate opk tests...when you have a faint line, does that mean you are getting close? I’ve only used the clear blue digital ones before and it only gives you the blank circle, flashing smiley face and a solid smiley face. My question is on the pregmate tests, if you aren’t even close would it just be one like and not a faint? Does this make sense what I’m asking? Thanks!
