The Clearblue digital pregnancy test with weeks indicator is the test that is as accurate as an ultrasound scan at dating pregnancy*. Its smart dual sensor not only tells you in words if you're pregnant or not pregnant, it also tells you how far along you are - the weeks since conception are shown as 1-2, 2-3 or 3+. You can test five days before your missed period (which is four days before your expected period). In lab testing, 98 per cent of pregnant results were detected the day before the expected period , 97 per cent two days before the expected period, 90 per cent three days before and 65 per cent four days before the expected period. (*Weeks result 97 per cent in agreement with later ultrasound dating scan. Based on studies of 187 women comparing result to ultrasound dating).

So Accurate - Also Tells You How Many Weeks The Clearblue Digital Pregnancy Test with Weeks Indicator is the first and only test that is as accurate as an ultrasound scan at dating pregnancy**. Its Smart Dual Sensor ™ not only tells you in words if you're 'Pregnant' or 'Not Pregnant', also tells you how far along you are.
