Frequently asked questions
When can I take a pregnancy test?▾
Standard urine tests are most reliable from the day of your missed period (~14 days after ovulation). Early-detection tests can work 6 days before missed period. Blood tests can detect pregnancy 7-10 days after conception.
How early can a pregnancy test detect pregnancy?▾
The earliest reliable detection is via blood test (~7 days post-conception). Early-detection urine tests work from ~10 days post-conception. Standard urine tests are most reliable after a missed period (14+ days post-conception).
Can I get a false negative?▾
Yes — taking a test too early is the most common cause. hCG levels need time to build up after implantation. If your period is late and the test is negative, retest in 2-3 days.
Are early-detection tests accurate?▾
Early-detection tests claim 99% accuracy on the day of expected period, but only ~75% accuracy 6 days before. Negative results 6 days early should be confirmed with a follow-up test if your period doesn't arrive.
Is morning urine better for pregnancy tests?▾
Yes — first morning urine has the most concentrated hCG. This is especially important when testing early. After missed period, time of day matters less.
What if my period is late but the test is negative?▾
Possible reasons: testing too early, irregular cycles, stress, hormonal changes, or recent contraceptive use. Wait 2-3 days and retest. If still negative and period doesn't arrive, see your healthcare provider.
