You can usually take a home pregnancy test from the first day of your missed period, but waiting a few extra days makes the result more reliable. Very early testing (before a missed period) can miss pregnancies because hCG levels are still low.

Quick Scoop

  • Most accurate time:
    • Take a urine pregnancy test on or after the first day your period is late.
* Accuracy is even higher if you wait about 1 week after the missed period.
  • Earliest possible time:
    • Some highly sensitive tests may detect pregnancy about 10–14 days after ovulation, which is roughly when your period is due in a regular cycle.
* Testing earlier than this raises the chance of a false negative because hCG may not be high enough yet.
  • If your cycles are irregular or you are unsure when your period is due:
    • Many health sources suggest waiting at least 21 days after unprotected sex (or sex where contraception might have failed) before testing.
  • Best time of day to test:
    • Use your first-morning urine for the strongest result, especially if you are testing close to your missed period or a bit early.
* After your period is clearly late, most modern tests can work any time of day, as long as urine is not very diluted.
  • Why timing matters:
    • After conception, the embryo implants in the uterus about 6–10 days later, and only then does the body start making hCG, the hormone that pregnancy tests detect.
* hCG then rises rapidly in early pregnancy, which is why waiting even a few days can turn a negative into a positive.
  • If your test is negative but you still think you might be pregnant:
    • Repeat the test in 2–3 days to a week, or speak with a healthcare professional about a blood test or further evaluation.
