Yes, sometimes: A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test. If a woman gets her normal regular period, then she is not pregnant, and a test is not needed.

A 21-year-old female asked:
Would a pregnancy test be accurate after one week of possible conception?

Usually not: An embryo usually will not implant into the uterine lining until after 7 to 9 days from fertilization. Only after implantation will the beta HCG hormone be produced. The pregnancy over-the-counter test detects the beta HCG hormone.
