How soon can a pregnancy test stick detect pregnancy?

How soon a pregnancy test can detect pregnancy varies individually, but generally, it can identify pregnancy 10 to 14 days after conception or approximately 14 days after sexual intercourse. This timeframe is calculated starting from embryo implantation, because after the embryo implants, the level of human chorionic gonadotropin (hCG) in a woman's body gradually increases. Pregnancy tests determine pregnancy by detecting hCG levels in urine. It should be noted that due to individual differences in physical condition and ovulation timing, the specific time at which pregnancy can be detected with a pregnancy test may vary. Some women might detect pregnancy shortly after conception, while others might require a longer time.
