How long adfter implantation can you test positive?

After implantation, it typically takes about 6 to 12 days for a pregnancy test to detect the hormone hCG in your urine. This means that testing positive can occur around 1 to 2 weeks after conception, depending on when implantation occurs and how sensitive the test is. For the most accurate results, it's often recommended to wait until the day of your expected period.
