If you think you might be pregnant, taking a pregnancy test is often the first step toward getting answers. Whether your period is late, you’ve noticed early pregnancy symptoms, or your birth control failed, it’s natural to want to know as soon as possible.
But how do pregnancy tests actually work, and when should you take one?
Understanding how pregnancy tests detect pregnancy can help you get the most accurate results and know what your next step should be. Read on to learn more, or contact Options for Women for free pregnancy testing and a safe space to get answers.
Pregnancy Tests Detect a Pregnancy Hormone
Pregnancy tests work by detecting human chorionic gonadotropin (hCG), a hormone your body begins producing after a fertilized egg implants in the lining of your uterus.
Implantation doesn’t happen immediately after sex. It typically occurs about 6 to 12 days after fertilization, and once implantation takes place, hCG levels begin rising rapidly.
Home pregnancy tests detect hCG in your urine. If enough of the hormone is present, the test will produce a positive result.
Because hCG takes time to build up, taking a pregnancy test too early can result in a false-negative. That doesn’t necessarily mean you’re not pregnant; it may simply mean your body hasn’t produced enough hCG for the test to detect yet.
Timing Matters
If you’re anxious to find out whether you’re pregnant, it can be tempting to test as soon as possible. However, waiting until the right time can improve the accuracy of your results.
For the most reliable result:
- Wait until after you’ve missed your period before taking a pregnancy test.
- If possible, use your first urine of the morning, when hCG is usually most concentrated.
- Follow the test instructions carefully.
- If your test is negative but your period still doesn’t begin after a few days, take another test or schedule an appointment with a healthcare provider.
Waiting can be difficult, but testing at the right time helps reduce the chance of receiving a false-negative result.
A Positive Pregnancy Test Is Only the First Step
A positive pregnancy test confirms that pregnancy hormones are present, but it doesn’t tell you everything you need to know about your pregnancy.
If your test is positive, an ultrasound is an important next step.
An ultrasound can determine:
- Whether the pregnancy is located inside the uterus
- Whether the pregnancy is viable, meaning you haven’t miscarried
- Approximately how far along you are
This information helps protect your health and gives you a clearer understanding of your pregnancy. An ultrasound can also identify an ectopic pregnancy, which occurs when a pregnancy develops outside the uterus. This condition can cause life-threatening complications and requires immediate medical treatment.
