Urine pregnancy tests will only be positive when you have sufficient HCG in your blood. If you are very early in your pregnancy, and the HCG level is below 25-50 mIU/mL, the test will be negative.
If you think you are pregnant, repeat the pregnancy test at home or at your health care provider's office.
