Tells you if you are pregnant or not with over 99% accuracy from the day your period is due
Super easy to read digital results removing any guess work
- Flashing hourglass symbol to show you the test is working
- ‘Pregnant’ or ‘Not Pregnant’ result shown on the screen
- If you are pregnant the test will then show you how many weeks it has been since you conceived (shown as 1-2, 2-3 or 3+ weeks) with 93% accuracy
You can test up to 5 days before your missed period (which is 4 days before your period due) - we know how hard it can be waiting to find out if you are pregnant
Fast results within 3 minutes
Can detect very small amounts (25 mIU/ml) of pregnancy hormone, human chorionic gonadotropin (hCG), in your urine

|

If you are testing before your missed period, you should use your first urine of the day but otherwise you can test at any time of the day
There is only one test in the pack and we understand that if you get a ‘Pregnant’ result you might want to double check your result and if you get a ‘Not pregnant’ result you will want to test again soon, so we wanted to let you know that you can also buy this test in a twin pack.
If you test before your period is due and get a ‘Not Pregnant’ result, there is still a chance that you might be pregnant. This is because the level of hCG may not yet be high enough to be detected, or you may have miscalculated the day your period is due, especially if your periods are irregular

Some women find reading a standard pregnancy test and trying to work out if there is a blue line there or not, especially when testing early stressful. This test removes any guesswork by showing you clear digital results on a screen. If you get a pregnant result it can be really exciting to know how far on you are too!

You can test up to 5 days before your missed period, which is actually 4 days before your period is due. If you are testing before your period is due remember to use your first urine of the day. Otherwise you can test any time of the day but don’t drink lots of liquid before taking the test.

Use your test as soon as you take it out of the foil wrapper.
Take off the cap and hold the tip in your urine stream for 5 seconds or in a sample of urine for 20 seconds.
Replace the cap and lay the test stick flat then wait for approximately 3 minutes. The hourglass symbol will flash to tell you the test is working, when it stops flashing your results will appear.
There are 4 possible results:

Results	How a Doctor would date the pregnancy based on a 28-day cycle

Pregnant 1-2	3-4 weeks
Pregnant 2-3	4-5 weeks
Pregnant 3+	5+ weeks

How does Clearblue Digital Weeks Indicator Pregnancy Test work?

When you are pregnant your body produces the pregnancy hormone human Chorionic Gonadotrophin (hCG). The amount of hCG in your body increases in the early stages of pregnancy. This test can detect very small amounts of hCG in your urine. (The sensitivity of this test is 25 mIU/ml). Based on the level of hCG in your urine, the test can provide an estimate of when you conceived.

How accurate is the test in detecting pregnancy?

In laboratory tests this test has been shown to be more than 99% accurate in detecting whether or not you are pregnant, when used from the day your period is due. If you test before the day your period is due and get a ‘Not Pregnant’ result, there is still a chance that you may be pregnant. Please see question 4 for more information.

How accurate is the test in telling me how many weeks since I conceived.

The Weeks Indicator is 93% accurate at detecting when you conceived. This estimate is based on the level of hCG in your urine. The level of hCG varies from woman to woman, and it is therefore possible that the Weeks Indicator might occasionally give misleading results.

If you are testing more than 6 weeks after conception the Weeks Indicator may give unexpected results. This is because the level of hCG in the urine is too high for the test to provide an accurate estimate of the time since conception.

When can I use the test?

You can use this test up to 5 days before your missed period (which is 4 days before your period is due). If you test before the day your period is due and get a ‘Not Pregnant’ result, there is still a chance that you may be pregnant.

Testing Early
Number of days before your period is due	% of samples from pregnant women giving a pregnant result
-1	98
-2	97
-3	90
-4	65

To work out when your period is due, calculate your usual cycle length by counting the number of days from the first day of your period until the day before your next period starts.

If you have irregular cycles, you should use your longest cycle in recent months
If you have no idea when your period is due, we recommend testing not less than 19 days after the last time you had unprotected sex

Can any medication or medical conditions affect the result?

Always read the manufacturers’ instructions for any medication you are taking before conducting a test. Fertility drugs containing hCG can give misleading results (these fertility drugs are usually given by injection and testing too soon after administration may give a false ‘Pregnant’ result). Other fertility therapies (such as clomiphene citrate), painkillers and hormonal contraceptives (e.g. contraceptive pill) should not affect the result. If you have recently stopped using hormonal contraception or are using fertility therapies like clomiphene citrate, your periods may be irregular, leading you to test too soon. If you have recently been pregnant (even if not carried to full term) you may get a false ‘Pregnant’ result. If you are approaching the menopause you may obtain a false ‘Pregnant’ result even though you are not pregnant. Ectopic pregnancy and ovarian cysts can give misleading results. Multiple and ectopic pregnancies can give misleading Weeks Indicator results. If you do get unexpected results you should discuss them with your Doctor

My test says I’m pregnant. What should I do?

Congratulation! Please see your doctor who can advise you on the next steps that you should take. Your doctor will estimate your due date based on the first day of your last period which is different to the date of conception show by the Weeks Indictor, which occurs around 2 weeks before your next period.

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 period is due, 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 loss during the early stages of pregnancy, known as ‘early pregnancy loss’. Sadly around 1 in 4 pregnancies end in early pregnancy loss. If you do get unexpected results, ask your doctor for advice.

My test says I’m ‘Not Pregnant’. What should I do?

You may not be pregnant, or the level of pregnancy hormone may not be high enough to be detected, or you may have miscalculated the day your period was due.

If you tested early, test again when your period is due
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, please see your Doctor
