I've been using OPKS this cycle consistently (not at the same time but every day) and am so confused. I know the instructions say don't read results after 5 mins but all of my other sticks have dried up where one line is def lighter than the other. Today though I fell back asleep and when I woke up it had dried up with both lines equal in color (last picture). Should I disregard or could this be my positive OPK?
