Can a Pregnancy Test Be Positive One Week After Conception?

Learn why pregnancy tests usually aren’t positive at 1 week after conception and when to take a test for accurate results.

Most pregnancy tests will not be positive at 1 week. Pregnancy tests measure the hormone hCG, which typically doesn’t rise to detectable levels until about two weeks after conception. This usually corresponds with the first day of a missed period, for those with regular cycles. So, taking a test only 1 week after ovulation or conception is likely too early for a reliable result. Wait until a missed period or at least two weeks after conception for a more accurate test.

FAQs & Answers

  1. When is the earliest I can take a pregnancy test for reliable results? The earliest reliable time to take a pregnancy test is usually around the first day of a missed period, about two weeks after conception, because hCG levels are typically detectable by then.
  2. Why might a pregnancy test be negative one week after conception? At one week post-conception, the hormone hCG is generally not yet at a detectable level in urine, making a pregnancy test result negative or unreliable.
  3. What hormone do pregnancy tests detect? Pregnancy tests detect the hormone human chorionic gonadotropin (hCG), which starts increasing after implantation of the fertilized egg.
