I understand that the clear blue testing is 99% accurate, but I bought 4 digital tests. My husband and I were excited by the fact that I was late and when I took the first digital test it said Pregnant 3+. After that, I took another one and it said Not Pregnant. Two more after that said Pregnant 2-3 and then Not Pregnant. I went to my doctor's and had a blood test and today we got the results back that we are in fact, not pregnant. It is so disappointing. We shared our initial news with our family and immediate friends because we have heard and read that it is practically impossible to receive a false positive, let alone two false positives, and everyone was so excited for us. It is both disappointing and defeating. How could this happen with a test that was supposed to be so clear and accurate? I would not recommend this product, as it caused me to leave work from excitement, call my mother, my husband, etc. We got so many people so excited for our first child, which never existed. I am truly saddened by this.
