If the test line is lighter than the control line, does that mean anything? I know it is negative, but does it mean you should start testing twice a day because the darker line is coming?

Or is it just a normal thing, these lighter lines...

Sorry if this is a novice question, but I'd love some advice. Don't want to pee in a cup excessively if I don't have to.

(and for reference, I'm on CD 10 with totally unpredictable length in cycles....anywhere from 28 to 37 days....)
