how early can you do a pregnancy test

You can take a pregnancy test as early as 6 days before your missed period (which is about 5 days before your expected period). Some highly sensitive home pregnancy tests, such as Clearblue Early Detection, can detect the pregnancy hormone hCG starting around this time. However, testing very early may yield a negative result even if you are pregnant because hCG levels might still be too low to detect. Testing on the day of your expected period or after will give you over 99% accuracy. If you test early and get a negative result, it is advised to test again a few days later or when your period is due. Also, for early testing, it is best to use the first urine of the day when hCG concentration is highest.
