Some early pregnancy tests, such as the Clearblue Early Detection Pregnancy Test, can tell you whether you are pregnant as early as 6 days before your missed period (5 days before you expect your period)1.
Visual signs give consumers confidence. The Clearblue® Early Detection Pregnancy Test provides early detection of hCG and can be used 6 days before the missed period (5 days before the expected period). The test is over 99% accurate from the day of the expected period8.
Clearblue Early Detection Pregnancy Test provides early detection of the pregnancy hormone. 71% of pregnancies can be detected 6 days before the missed period (5 days before the expected period) and 94% of pregnancies can be detected 5 days before the missed period (4 days before the expected period).
The short answer? Most home pregnancy tests can be done from the first day of your missed period. If you're not sure when you're having your next period—or if your period is irregular– take the test at least 10 days after you had unprotected sex.
Our pregnancy tests can detect the HCG pregnancy hormone as early as 7 days after conception or 21 to 24 days after the first day of your last menstrual period (LMP). Most pregnancy tests aren't accurate until at least 7 days after fertilization, which is when the embryo implants into your uterus.
What level of hCG can pregnancy tests detect? Generally, most home pregnancy tests claim to detect hCG levels from 25 mIU/ml. However, some tests, such as the Clearblue Early Detection Pregnancy Test, are so sensitive they can detect hCG levels as low as 10 mIU/ml.
More often than not, a faint line on a pregnancy test indicates a positive result. Though, it's likely that the pregnancy is early days. 'A faint line is usually a sign of very early pregnancy and is most common when women have taken a test before a missed period,' says Marie.
This usually ranges between a couple of minutes up until 10 minutes later. If you see a positive result beyond this time frame, you may be left second-guessing the results. However, always remember that a pregnancy test result is only accurate within 10 minutes.
Know this: All Clearblue® pregnancy tests are over 99% accurate from the day you expect your period. False positives very rarely occur, and are often due to medical conditions or certain medications. False negatives, while more common, typically occur due to testing too early or drinking too much liquid before testing.
If you feel as though you're pregnant but got a negative home pregnancy test result, your symptoms could be down to premenstrual syndrome (PMS) or you may have taken the test too early.
Excess fluids can impact the accuracy of the test results, so if your urine is diluted or pale yellow, hold off on taking a test. Diluted urine tends to also have diluted hCG levels which can skew the test results. Take a test when you naturally need to pee.
Note: A Control (C) line may appear in the result window within a few minutes but a Test (T) line may take as long as 15 minutes to appear. Note: After 20 minutes the result might become inaccurate.
A line on a pregnancy test a positive result if: There is a visible dye in the line, even if the color is faint. The line appears within the period specified on the instructions, which is usually 3–5 minutes.
Nearly as sensitive when testing early
Clearblue Early Detection is another great choice for early testers. It's slightly less sensitive than First Response Early Result, but it has a wider absorbent tip and a longer handle.
You might get a false-negative if you: Take the test too early. The earlier you take a home pregnancy test, the harder it is for the test to find HCG . For the most accurate results, take a home pregnancy test after the first day of a missed period.
First Response Early Result Pregnancy Test
Both our experts agree that First Response Early Results is one of the most sensitive home pregnancy tests available with the ability to accurately test levels of hCG five days before your expected period.
Symptoms of rising hCG levels can include fatigue, nausea/vomiting (aka morning sickness), dizziness or light-headedness, breast tenderness, and feeling emotionally sensitive.
The first sign of pregnancy is usually missing a period, about 2 weeks after you've conceived. This isn't always reliable and if your periods aren't regular you might not notice you've missed one. Some women have a bit of bleeding as the egg embeds. Many women also experience tender breasts.
Your growing uterus is pulling and straining the muscles that support it. You may feel sharp pains or just a mild pulling sensation. It often occurs when you cough, sneeze, stand up, sit down, roll over, or during sex.
If you were exposed to COVID-19 and do not have symptoms, wait at least 5 full days after your exposure before testing. If you test too early, you may be more likely to get an inaccurate result. If you are in certain high-risk settings, you may need to test as part of a screening testing program.
If you tested positive for COVID-19 but have not had any symptoms: Isolate for at least 5 days after you tested positive for COVID-19. You can leave isolation after 5 full days if you have not developed any symptoms. If you develop symptoms after testing positive, your 5-day isolation should start over.
