I have an OPK question too (thought I may as well ask it here instead of starting a new topic with the same title!!) - this is my first cycle using them.
I know that the test line has to be "as dark as or darker than" the control line. BUT if the test line is light, does that mean you are getting closer to ovulation and it should be dark in the next day or two?
Yesterday and the day before I had no test line at all, but today there is a light line! So am I getting close to ovulation, or does a light line not mean anything at all? I hope someone knows what I'm rambling about
