I have been using First Response Early Result. Today, I am 9dpo and have got negatives. I hope I am not out for this month, but I am losing hope. My question is.... Between first response early response and clear blue, which one is better? I would prefer the one that gives the most accurate results earliest. Does Clear Blue give a lot of false positives? I have heard blue dye tests are not as accurate. But then I read that first response sometimes do not yield a positive test until days after a missed period. What is the best test to use?
