An example of the daily hCG rise in early pregnancy urine samplesDay 0 indicates the day the period was expected.
Not all pregnant women who test before the day of their expected period will obtain a 'pregnant' result.
All Clearblue Pregnancy Tests are rigorously tested using early pregnancy urine samples from women whose LH surge day is known and from which the day of expected period can be estimated.7 Using these samples Clearblue can assess the proportion of women expected to have sufficient hCG in their urine sample to generate a 'pregnant' result, on each specific post-conception day. The Clearblue Advanced Pregnancy Test with Weeks Estimator is the latest innovation in pregnancy testing.
It is the FIRST and ONLY pregnancy test to provide an estimate of time since ovulation, for women testing pregnant.
The Clearblue Advanced Pregnancy Test with Weeks Estimator gives the earliest estimate of time since ovulation. The Clearblue DIGITAL Pregnancy Test with Smart Countdown features a unique progress indicator (Smart Countdown) to reassure the user the test is working and indicate when they can expect the result to appear. Over 25 years of consumer research has given Clearblue an exceptional understanding of our consumersa€™ needs, allowing us to develop the next step in visual home pregnancy tests.

The Clearblue Advanced Pregnancy Test with Weeks Estimator is an over-the-counter urine hCG test which is intended for the detection of pregnancy. This test contains a 'Weeks Estimator.' The 'Weeks Estimator' is meant solely as an estimate for the consumer and is not intended as a substitute for a doctor's clinical diagnosis.
This test cannot be used to determine the duration of pregnancy or to monitor the progression of pregnancy. Home pregnancy tests simply detect the hormone Human Chorionic Gonadotropin (hCG) through a urine sample.
Many home pregnancy tests can detect hCG as early as 10 days before a missed period; however, for the most accurate results, it is recommended that you test after a missed period. To get the best results early on, doctors suggest testing first thing in the morning because that urine will have the highest concentration of hCG. The data above is based on the fact that in each menstrual cycle there is an about 25% chance of getting pregnant as well as a scientific study published by Wilcox in JAMA in 2001. The chances of having a negative pregnancy test, based on personal experience AND the above chart which does seem accurate,  and being pregnant still (say a week or more after your period is due) is highly rare.
For some, the HCG is obviously not yet built up enough to be detected by the test being used.


I had the symptoms, the pains, even the positive ovulation test, but I soon learned that sometimes the body gears up to ovulate and then fails for no apparent reason.
Back then I had heard of some pregnant women getting positive ovulation tests, so I was further confused. If women choose to test early, the likelihood of detecting pregnancy before the day of the expected period is clearly displayed in the product packaging. Using different a€?Lotsa€™ of pregnancy test gave a false positive rate of between 0% and 0.3%. Clearblue Advanced Pregnancy Test with Weeks Estimator determines the level of hCG in urine to estimate weeks since ovulation.
Traditionally, the date of the first day of the Last Menstrual Period (LMP) is used to determine pregnancy duration as this is often the only information available in early pregnancy. Clearblue has been shown to be over 99% accurate from the day of the expected period when compared to a reference method in laboratory studies using urine samples supplied for pregnancy testing.

When compared to a laboratory reference method, Clearblue Digital Pregnancy Test has been shown to be over 99% accurate from the day of the expected period when using urine samples supplied for pregnancy testing.
Clearblue Digital Pregnancy Test can be used as early as 4 days before the period is expected. The test detects hCG in some cases from 4 days before the expected period (which is 5 days before the day of the missed period). Your doctor determines how many weeks pregnant you are based on the first day of your last menstrual period and ultrasound results.
Many home pregnancy tests can determine results even before a missed period, however, the results of these tests are less accurate early on.
The pregnancy hormone hCG is created when a placenta is developing and can be detected sometimes just after the fertilized egg has implanted in the uterus.
The rate of accuracy is much lower if you take the test early and may show a negative result even when are pregnant. If your test came up negative and you've missed a period, you may need to test again in a few days. But there are people that fall into that 1% who claim they don’t get a positive test until much further along. The woman may assume that she did, but then the period does not come on time, and of course she will think that means that she’s pregnant. Any woman who tests early and gets a negative result, but still suspects pregnancy, should test again on or after the day their period is expected.


All positive results were for women who were over 50 years of age.10 At Clearblue we believe that consumers need a result they can be confident in, and therefore we provide products that deliver over 99% accuracy from the day of the expected period. Pregnancy duration has been scientifically validated as being related to absolute quantities of hCG in urine7 and can be used to give an estimation of time since ovulation in weeks, relative to the surge in luteinizing hormone (LH).
Levels of urinary human chorionic gonadotrophin (hCG) following conception and variability of menstrual cycle length in a cohort of women attempting to conceive. However, the pregnancy hormone increases rapidly in early pregnancy and Clearblue PLUS Pregnancy Test can be used to test up to 4 days before the expected period, which is 5 days sooner than waiting for the missed period. It is for general information only with no warranties, representations or undertakings, express or implied, and does not constitute medical advice. This test provides a different estimate that cannot be substituted for a doctora€™s determination of gestational age. If the test repeatedly comes up negative and you believe you are pregnant, you should speak with your doctor as soon as possible. For example, the brand First Response's are 69% accurate in women four days before an expected period, 83% accurate three days before, 93% accurate two days before and 93% accurate the day before the expected period. Also, do not drink extra liquids to make yourself have to use the bathroom again, as this will dilute urine.
The result is displayed on an easy-to-read digital display, as a€?Not Pregnanta€™ or a€?Pregnanta€™ together with an estimate of weeks since ovulation (1-2, 2-3, 3+ weeks). In clinical testing, Clearblue PLUS Pregnancy Test detected the pregnancy hormone in 56% of women when testing 4 days before their expected period, 88% at 3 days before their expected period, 97% at 2 days before their expected period, and 98% at 1 day before their expected period.
Only your doctor can provide a reliable estimate of gestational age and only your doctor can monitor pregnancy progression.
I have read time and again that you are more likely to get a false negative HPT result and be pregnant, than to have a false positive result and not be pregnant. The most common reason, and this happened to me once where I swore I had to be pregnant, was that I did not ovulate like I thought I had. This can happen up to 1-2x’s per year in perfectly healthy, fertile women, without any need for concern. It brought on an early period.  If you are worried about anything for any reason, do see your doctor.
In clinical testing, Clearblue Digital Pregnancy Test detected the pregnancy hormone in 51% of women when testing 4 days before their expected period, 82% at 3 days before their expected period, 90% at 2 days before their expected period and 95% at one day before their expected period. Something I never knew before, but when you are not trying, you can miss these things far more often.
