B) Completely immerse the tip only in a sample of your urine collected in a clean, dry container for a full 20 seconds. 

  • Replace the cap and lay the test stick flat. 
  • Start timing. 

WAIT 3 MINUTES before reading your results.

A line in the control window may start to appear quickly but you MUST wait 3 minutes before reading your result.

Frequently asked questions

How does Clearblue® Ultra Early work?

When you are pregnant your body produces the pregnancy hormone hCG (human Chorionic Gonadotrophin). This test can detect tiny amounts of hCG in your urine (the sensitivity of this test is 10 mIU/ml).

⌛ When can I test with Clearblue® Ultra Early?

You can test up to 6 days before your missed period, which is 5 days before you expect your period.  If you test before your expected period and get a ‘Not Pregnant’ result, there is still a chance that you may be pregnant. See chart below for results of clinical testing with early pregnancy samples.

My test says I’m ‘Pregnant’. What should I do?

You should see your doctor who can advise you on what steps you should take next.

My test says I’m ‘Not Pregnant’ but I still think I may be. What should I do?

You may not be pregnant, or the level of hCG may not yet be high enough to be detected, or you may have miscalculated the day of your expected period. If you tested early, test again when your period is expected. If your period is overdue, test again in 3 days’ time.  If this test gives you a ‘Not Pregnant’ result and you still have not had your period, see your doctor.

I previously tested ‘Pregnant’ but have tested again and got a ‘Not Pregnant’ result, or my period has started. What does this mean?

Whilst the test is over 99% accurate at detecting the pregnancy hormone from the day of your expected period, it’s possible to get a pregnant result and find out later that you’re not pregnant (i.e., you may later get a not pregnant result, or your period may start). This may be due to natural loss during the early stages of pregnancy, known as ‘early pregnancy loss’, which sadly is not uncommon, as around 1 in 4 pregnancies end in early pregnancy loss. If you do get unexpected results, ask your doctor for advice.

Can any medication or medical conditions affect the result?

Always read manufacturers’ instructions for any medication you are taking before conducting a test. Fertility medications containing hCG can affect the result. Ectopic pregnancy and recent pregnancy even if not carried to full term can cause misleading results. If you are in or approaching the menopause you may obtain a false pregnant result even though you are not pregnant. The test should not be affected by other fertility therapies, painkillers, alcohol, antibiotics, or the contraceptive pill. If you get unexpected results discuss them with your doctor.

When I used the test the colour change tip did not turn completely pink. What should I do?

You may not have applied enough urine; however, if the blue line in the control window appears within 10 minutes of taking the test then the test has worked.

I have taken the test but no blue line has appeared in the control window. What should I do?

If it is more than 10 minutes since you took the test, then the test has not worked. This may be because:

  • The colour change tip was not kept pointing downwards or the test stick was not laid flat after urine was applied.
  • Too much or too little urine was used. 

Test again, using a new test stick, taking care to follow the instructions. You may wish to collect a sample of urine and test using the ‘Collected Sample’ method. 


What if I am unsure of my result?

Refer to images A-D: 



Picture A: Your result is ‘Not Pregnant’. If you still think you might be pregnant, see relevant question above.

Pictures B-D:  Your result is ‘Pregnant’. The appearance of the line in the result window may vary, however, it is still a ‘Pregnant’ result no matter how faint or dark it is.

  Picture B: This is more likely when you are testing before your period is expected when your hCG levels may be relatively low. 

  Picture C: This is not unusual when you are testing on or around the day your period is expected. 

  Picture D: This is more likely to occur when you are testing more than a few days after your period was expected as hCG levels are higher.


If you are still unsure of your result, you should wait at least 3 days before testing again, taking care to follow the instructions.
