It is generally recommended to wait at least 9 to 12 days after unprotected sex before taking a pregnancy test, especially if your period is irregular or you don't know when it is due. Most accurate results come after you have missed your period, which is typically about two weeks or more after the unprotected sex. Pregnancy tests detect the hormone hCG, which starts to be produced after implantation, usually 6 to 12 days after fertilization. Taking the test too early may result in a false negative because the hormone levels might not yet be high enough to detect. Here are key points:
- If you track your period and it’s regular, wait until your period is late to test.
- If your period is irregular or unknown, test about 9 to 12 days after sex or about two weeks for more reliable results.
- Early pregnancy tests are more accurate after the first day of a missed period.
- For the earliest possible detection, some sensitive tests can be taken around 10 to 14 days after unprotected sex, but accuracy is best if you wait longer.
So, the best time to take a pregnancy test is about two weeks after unprotected sex or when your period is late to ensure the most accurate result.
