The packaging on my OPK's says to dip the strip for three seconds. Usually they come out fine, but occasionally I'll get one that looks a bit funny. Not as if it's faulty, but like the control line is a bit lighter than usual or partially faded. Is this normal, or should I try dipping it for a couple extra seconds? I don't want to over-saturate the test, but I've heard it's pretty hard to do that.
Thanks in advance for any tips! I'm really looking forward to seeing a positive result one of these days!
