Hi there...try to calm yourselves first. Unfortunately you haven't mentioned after how many days of unprotected sex, she got the urine
pregnancy test done. Urine pregnancy test usually becomes positive 6-10 days after sexual contact. So it is usually done 10 days after missed regular period. Also urine pregnancy tests are 99% accurate. There is a chance of false positive. So it is better you consult a obstetrician as soon as possible for further tests.
