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 on the digital display if you’re pregnant or not, but it also tells you how far along you are. With this home pregnancy test kit, you can test 5 days before your missed period (which is 4 days before you expect your period). 65% of pregnant results can be detected 5 days before your missed period.
