New Pregnancy Test Tells How Many Weeks You Are

Katlyn Joy | 9, September 2013


Finally, American women will have the choice to choose an upgraded pregnancy test that has been available to European women since 2008. The Clearblue Advanced Pregnancy Test with Weeks Estimator is the only test that can not only tell you whether you are pregnant but also how many weeks pregnant you are as well.

According to the company's website, 78 percent of women surveyed said it's very important to know how many weeks pregnant they are.

The one of a kind technology uses two testing strips to estimate the point in pregnancy. They calculate from ovulation and give results as 1-2 weeks, 2-3 weeks or 3 plus weeks pregnant.

The digital display will read out "Not Pregnant", or "Pregnant" and 1-2 for a pregnancy dated as 1-2 weeks, 2-3 for a pregnancy estimated at 2-3 weeks in duration or 3+ for a pregnancy of 3 or more weeks. Keep in mind if you have been pregnant 1-2 weeks since ovulation, the doctor will date your pregnancy as 3 to 4 weeks along; if test says 2-3 weeks, the doctor will say you are 4 to 5 weeks pregnant, and if your test says 3+ weeks the doctor will estimate the pregnancy as 5 or more weeks along.

The test is over 99 percent accurate in determining if you are pregnant, and 93 percent accurate in determining how far along the pregnancy has progressed in weeks. Since doctors date pregnancies from the last menstrual period and approximately 70 percent of women are unsure of their LMP, a test such as Clearblue Advanced Pregnancy Test with Weeks Estimator can be an important tool in dating a pregnancy.

Most doctors, 84 percent, according to Clearblue, state that the test offers helpful information. Most doctors will not perform an ultrasound until about 8 to 12 weeks. This early ultrasound will help date a pregnancy, so Clearblue users will have this specific information on their pregnancy weeks sooner.

Clearblue detects the hCG in the urine, and this hormone increases rapidly in early pregnancy. The Clearblue Advanced Pregnancy Test can be used up to four days before your expected period. However, if you get a negative result when testing early, you may need to retest later to get a more accurate reading.

The company website breaks down the timing and accuracy of results as follows:

  • 4 days before period: 65 percent accurate.
  • 3 days before period: 90.6 percent accurate.
  • 2 days before period: 97.9 percent accurate.
  • 1 day before period: 98.8 percent accurate.
  • 0 days before period: 99 percent accurate.

For those who have not kept good track of previous menstrual periods, the company advises testing at the latest 19 days after last unprotected sex occurred. If you have irregular cycles, then go by the longest cycle in recent months to determine when you should test.

The company advises if you receive a "Not Pregnant" result, and retested a few days later with same result but still have not gotten your period, to seek advice from your physician. Likewise, if you tested Pregnant but then got your period, you should see your doctor.

Some medical conditions and medications can affect the reliability of the test results. For instance certain fertility drugs contain hormones which can give testers false positives. These drugs include Pregnyl, Profasi or Clomid, among others.

If you were recently pregnant, even if you didn't go to term and had a miscarriage or abortion, you may still get a Pregnant result even if you are not.

If you have ovarian cysts or an ectopic pregnancy, you can get inaccurate results, too.
Also, those carrying twins or more will often get an inaccurate weeks pregnant result as hCG levels will be higher than normal for the point in pregnancy due to the multiples.
