Pregnancy: The first day a urine pregnancy test usually becomes positive is the first day of a missed period. It is possible that you conceived this last week but you must wait a few days to see if implantation has occurred and you are officially pregnant as signified by pregnancy hormone being found in your blood and urine from the developing placenta. Check a pregnancy test if you don't get your period.
