You can take a pregnancy test as early as about 6 to 12 days after fertilization, but for the most reliable and accurate result, it is best to wait until the first day of your missed period. Here are important details on timing:
- Early detection tests can detect pregnancy hormone (hCG) in urine up to about 5 days before your expected period, but results are more accurate the closer you get to the missed period.
- Most standard home pregnancy tests are accurate from the day your period is due or the first day of your missed period, which is roughly 14 days after fertilization.
- If your menstrual cycle is irregular or you do not know your period date, it's recommended to wait about 3 weeks after unprotected sex to take a test.
- Morning urine is the ideal sample for testing because it contains the highest concentration of hCG, especially important when testing early.
- For a more reliable result, waiting a week after your missed period can improve accuracy.
In summary, while you can test early with sensitive kits a few days before your expected period, the best time to take a pregnancy test is on or after the day your period is late. If uncertain, waiting 1-2 weeks post missed period or 3 weeks after potential conception provides greater accuracy.
