You’re generally supposed to take a pregnancy test after a missed period , or at least around 2 weeks after unprotected sex, to get the most reliable result.

Best time to take a test

  • Most guidelines say to test from the first day of a missed period for dependable results.
  • If your cycles are regular, that usually means about 14 days after ovulation or conception.
  • If your cycle is irregular or you’re not sure when your period is due, test at least 21 days after unprotected sex.

How early is “too early”?

  • Many home tests may pick up pregnancy about 10–14 days after conception , but testing this early increases the chance of a false negative.
  • Some “early detection” brands can show positive results a few days before a missed period , but accuracy is lower than if you wait.
  • Waiting a week after your missed period gives the highest chance that the result reflects your true status.

Best time of day

  • For the most accurate result (especially early), use your first urine of the morning , when the pregnancy hormone hCG is most concentrated.
  • If you test later in the day, try not to drink a lot of fluids for a few hours beforehand so your urine isn’t too diluted.

When you should definitely test

  • You’ve missed your period or it’s more than a month since your last one.
  • You had unprotected sex (or birth control failed) 2–3 weeks ago.
  • You’re noticing early pregnancy signs like sore breasts, nausea, or unusual tiredness along with possible cycle changes.

If the result is negative but you still think you’re pregnant

  • A negative test early on doesn’t always mean you’re not pregnant; it can just be too soon for the hormone to show.
  • If your period still doesn’t come, repeat the test in about a week , or contact a healthcare professional for a blood test or further advice.

If you’re ever unsure, have severe pain, heavy bleeding, or feel unwell, seek urgent medical care or contact a healthcare provider right away.

TL;DR: For most people, the safest rule is: wait until the day your period is late (or about 2–3 weeks after unprotected sex) , test with first morning urine, and repeat in a week if your period still hasn’t arrived and the first test was negative.
