It is this hormone that Clearblue Digital Pregnancy Test with Conception Indicator detects in your urine, and it is sensitive enough that you can use it up to 4 days before your period is due. An optical reader in the Test Stick interprets the result for you and shows this on a digital display: ‘Pregnant’ or ‘Not Pregnant’. If the result is ‘Pregnant’ the Test also monitors the concentration of hCG, and provides an estimate of how many weeks ago you conceived: 1-2, 2-3 or 3+. This is displayed together with the ‘Pregnant’ result.

Testing Early
Clearblue recommend that you test from the day your period is due. However, the pregnancy hormone increases rapidly in early pregnancy and Clearblue can be used to test up to 4 days before your period is due. In clinical testing with early pregnancy samples Clearblue Digital Pregnancy Test with Conception Indicator gave the following results:
