Most home pregnancy tests can detect hCG as early as about 10 days after conception, which is roughly 4 weeks from the first day of your last period. For the best accuracy, it's recommended to wait until you've missed your period to take the test. This is when the level of hCG in the urine is typically high enough to be detected by a home pregnancy test, leading to a positive result if you're pregnant.
