The best time to test for pregnancy is typically from the first day of a missed period. Some highly sensitive pregnancy tests can detect pregnancy hormones (hCG) a few days before the missed period, but for the most accurate result, it is recommended to wait until the missed period or even a week after the missed period. Testing too early may result in a false negative because the hormone levels may not be high enough to detect. It is also advised to use the first morning urine for testing, as it contains the highest concentration of hCG. If a menstrual cycle is irregular or the date of the next period is unknown, waiting at least 21 days after unprotected intercourse is a good guideline. Blood tests done by healthcare providers can detect pregnancy earlier than urine tests. In short:

• Best time: From the first day of a missed period
• Early sensitive tests: Up to 4-5 days before expected period, but less accurate
• Irregular cycles: Test at least 3 weeks after unprotected sex
• Use first morning urine for best results

This approach balances early detection possibilities and accuracy to avoid false negatives.
