Week 4- birth: A pregnancy test will be positive as soon as the first day of your missed period. For accurate testing, the first morning urine should be used. You can repeat the test with a different brand if you want to double check. The initial signs of pregnancy are breast tenderness and enlargement, nausea and dizziness. The test measures hCG which is a hormone that is produced by the placenta.
