Why don't I get dark ops strips when I test, like the two lines will be there but I see some of you girls having blazinggggggg dark lines???? When I test on clearblue advance I get my flashy smile then days later a solid smile but on the opk strips it's never dark at all ever. What does this usually mean? Clearblue is get the smiley opk test strips just two light lines.is something wrong?
