Shibby, an OPK is not positive unless the test line is just as dark or darker than the control line. Also, its not common to have a "fade in" pattern with OPKs. It would be great if that happened, so you would have an idea if ovulation is approaching. Truth is OPKs do work if used and read properly, but they are also a pain in the rear. Its best to test in the early afternoon and when you have restricted fluids for a couple of hours beforehand. It may take you a few cycles to get the hang of them. I had very irregular cycles, and OPKs were my only hope for predicting ovulation, and it took me a few cycles to really know how to use them. I suggest using them everyday until you get the positive! Good luck!
