Usually a pregnancy test will pick up the pregnancy hormone by the first or second day of your missed period if you are pregnant, but many tests suggest that you wait a week after you miss your period.
Most of blod and urine pregnancy tests measure the level of hormone called hCG, which is created after the egg is fertilized. Different pregnancy test may have different sensitivity, so it will depend on particular test type when it will test positive. However usually a pregnancy test will test positive after first few days of pregnancy.
Many pregnancy tests can ascertain pregnancy within the first week. If you believe yourself to possibly be within the second week, you could take a pregnancy test now.
