When to Take a Pregnancy Test
You can take a pregnancy test as soon as 6 days after you have unprotected sex, but the most accurate results are typically obtained after you have missed your period. If you have a regular cycle, this means about 14 days after ovulation.
If you have an irregular cycle, it is best to wait until at least 1 week after your expected period date to take a pregnancy test.
Accuracy of Pregnancy Tests
Pregnancy tests are very accurate, especially when taken after you have missed your period. Most pregnancy tests have an accuracy rate of over 99%. However, there are a few things that can affect the accuracy of a pregnancy test, such as:
- Taking the test too early
- Not following the instructions carefully
- Using a test that is expired
- Having a medical condition, such as a miscarriage or ectopic pregnancy
Results of Pregnancy Tests
Pregnancy tests work by detecting the presence of a hormone called human chorionic gonadotropin (hCG) in your urine. hCG is produced by the placenta after a fertilized egg implants in the uterus.
If you are pregnant, the pregnancy test will display a positive result. If you are not pregnant, the pregnancy test will display a negative result.
If you get a positive pregnancy test result, it is important to contact your doctor to schedule a prenatal appointment.
Here are some tips for taking a pregnancy test:
- Read and follow the instructions on the pregnancy test carefully.
- Take the pregnancy test first thing in the morning, when your urine is most concentrated.
- Do not eat or drink anything for at least 30 minutes before taking the pregnancy test.
- Empty your bladder completely before taking the pregnancy test.
- Wait the full amount of time specified in the instructions before reading the results.
If you have any questions or concerns about pregnancy tests, talk to your doctor.
