When can I use the Clearblue Digital Pregnancy Test?

Clearblue recommends that you test from the day your period is due. However, Clearblue Digital Pregnancy Test can be used up to 4 days before your period is due. If you test before your period is due and get a ‘Not Pregnant’ result, there is still a chance that you may be pregnant but that your hormone level is still not high enough for the test to detect.

In clinical testing with early pregnancy samples Clearblue Digital Pregnancy Test gave the following results: 51% of women received a ‘Pregnant’ result 4 days early, 82% of women 3 days early, 90% of women two days early and 95% of women 1 day early.

How does the Clearblue Digital Pregnancy Test work?

Average levels of hCG circulating in your body during pregnancy and after giving birth. Point 1 is Implantation and Point 2 is birth.

Week 3
As soon as a fertilised egg is implanted in the lining of your womb (implantation), your body starts producing the pregnancy hormone, human Chorionic Gonadotrophin (hCG).  Although the length of the menstrual cycle varies between women, many women will have their next period 12-16 days after ovulation.  If you are pregnant, in most women, by the day your period is due, the level of hCG in your body will be detectable by a Clearblue pregnancy test.

Week 4
If you do a Clearblue Pregnancy test and your result is 'Pregnant', your first step is to make an appointment with your doctor for advice on how best to look after yourself and your baby during these crucial first weeks of pregnancy, and also later on.  If you do a Clearblue Pregnancy test and the result is 'Not Pregnant', but you still think you might be pregnant, wait for 3 days and test again.  The level of hCG increases so rapidly that the level will be much higher 3 days after originally testing, and will show if you are pregnant.

Week 5
The level of hCG doubles approximately every 2-3 days. hCG helps to maintain the pregnancy. It is thought that this is the hormone responsible for morning sickness.

Week 7-12
Sometimes between weeks 7-12, the level of hCG peaks and then drops almost as rapidly as it increased, which is why morning sickness often drops off after the first 12 weeks or so of pregnancy.

Week 15
The level of hCG then stays at a steady, elevated level for the rest of the pregnancy and for up to 3 weeks after giving birth.  The level of hCG is elevated above normal levels for up to 9 weeks if you have had a miscarriage or termination.  If you do a Clearblue Pregnancy test during this time, it will be impossible to know if the 'Pregnant' result is caused by a new pregnancy or by the residual hCG from your previous pregnancy.  In this situation, it is worth making an appointment with your doctor.

The Clearblue Digital Pregnancy Test works by detecting the pregnancy hormone in your urine and is over 99% accurate when used from the day your period is due. You can use it up to 4 days before your period is due but if you get a ‘Not Pregnant’ result, you should test again when your period is due. The levels of pregnancy hormone in your urine may not be high enough to be detected yet.

With a Clearblue Digital Pregnancy Test, an optical reader encased in the Test Stick interprets the result for you and shows your result in words: either ‘Not Pregnant’ or ‘Pregnant’ with an indication of how many weeks.

The Clearblue Digital Pregnancy Test is quick and easy to use, and produces a result within 3 minutes.

How to interpret your results

Your doctor will calculate your stage of pregnancy based on the first day of your last period. The Conception Indicator tells you how many weeks ago you conceived. Conception occurs approximately 2 weeks before your next period is due.
