Hello! I used a different brand of OPK for a cycle or two sometime last year and got lovely dark positives. I have decided to start testing again and am using a different brand this month of OPK but I am having a hard time deciding if it is positive or not yet! If you zoom in you can see it's not *quite* as dark as the control???
