Quick Answer: Testing Timeline After Unprotected Sex
You should wait at least 14 days after unprotected sex to take a pregnancy test for the most reliable results. While some early detection tests claim to work sooner, waiting until after your missed period (typically 21 days after unprotected sex) provides the most accurate results.
Detailed Timeline: When to Test After Unprotected Sex
- Within 72 hours: Consider emergency contraception options
- 7-10 days: Too early for accurate test results
- 14 days: Minimum wait time for pregnancy test after unprotected sex
- 21 days: Most accurate testing time (after a missed period)
Why You Need to Wait After Unprotected Sex
After unprotected sex, your body needs time to produce detectable levels of the pregnancy hormone (hCG). Testing too soon after unprotected intercourse can lead to false negative results. Here's what happens:
- Fertilization occurs within 24 hours of unprotected sex
- Implantation takes 6-12 days after fertilization
- HCG hormone becomes detectable 2-3 days after implantation
Important: Testing Too Early
Taking a pregnancy test too soon after unprotected sex is one of the most common mistakes.
Even if conception occurs, the test won't be accurate until your body produces enough hCG hormone.
