You can get the most reliable result by testing after your period is late. What to know
- Best timing: On the first day of a missed period, or up to a week after a missed period for higher accuracy. Waiting a bit longer (about 1 week after the missed period) increases accuracy because hCG levels rise over time.
- Early testing notes: Some tests can detect pregnancy before a missed period, but a false negative is more likely when testing too early.
- If cycles are irregular or hard to predict: Test at least 21 days after any unprotected intercourse if you’re unsure when your next period is due, to reduce uncertain results.
- Morning urine often yields the strongest result for standard tests, especially when testing after a late/missed period.
Practical steps
- If your period is late by a day or two, you can test, but you may want to wait 1–2 additional days for clearer results.
- Follow the specific test’s instructions carefully (timing, whether to use first morning urine, etc.).
- If you get a negative result but still suspect pregnancy (due to symptoms or continued missed period), retest a few days later or contact a healthcare professional for guidance.
Bottom line
- Most reliable results come from testing at least on the day your period is late, or about a week after a missed period. Testing earlier can yield false negatives, while testing later improves accuracy.
