Okay so last month I used my first cycle of opks and they worked perfectly this time I've had so much trouble with getting it to work. I used clear blue digital and I think I got a bad batch because all my test strips won't show up and if they do its way longer than five minutes and they almost look like they have water lines through them. My cm was sticky and scretchy yesterday and then super watery today and yesterday was supposed to be my most fertile day. But after using my test strip it said I wasn't ovulating I'm so confused and need help. Could I have just got a bad batch or?
