I have never written a review for anything on the internet, but felt compelled to say that I received a false positive with the digital Clearblue pregnancy test. I have never heard of false positives with HPTs until it happened to me. I called the company, and they said that it's extremely rare unless you're taking fertility medications (which I never have). Very heartbreaking and frustrating that a 99% accurate digital test produces a false positive - I understand false negatives and pregnancy tests, but I am really upset about a false positive. I would not use this product again.
