A ‘Pregnant’ result may appear in as fast as 1 minute when testing from the day you miss your period (which is the day after you expect your period). Make sure a blue line is also present in the control window before reading your result. You must wait 3 minutes to confirm a ‘Not Pregnant’ result, or when testing before you expect your period. If no blue line appears in the control window within 10 minutes the test has not worked (refer to question 6).
