If you think you might be pregnant, taking a pregnancy test is the first step toward getting answers.

Whether your period is late, you’ve noticed pregnancy symptoms, or your birth control failed, you probably want to know as soon as possible. But have you ever wondered how pregnancy tests actually work?

Understanding how pregnancy tests detect a possible pregnancy, and when they’re most accurate, can help you feel more confident in your results and know what to do next.

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.

Here’s how the process works:

• Ovulation occurs, and an egg is released from your ovary.
• If a sperm fertilizes the egg, it begins traveling toward the uterus.
• The fertilized egg implants in the uterine lining, usually 6 to 12 days after fertilization.
• Once implantation occurs, your body begins producing hCG.

Pregnancy tests are designed to detect this hormone in your urine.

Because hCG isn’t produced immediately after unprotected sex, taking a pregnancy test too early can result in a false negative, meaning the test says you’re not pregnant even though you are.

Timing Matters

If you’re eager for answers, it can be tempting to take a pregnancy test as soon as possible.

However, waiting until after you’ve missed your period gives you the best chance of getting an accurate result.

For the most reliable results:

• Use your first urine of the morning, when hCG levels are usually the highest.
• Carefully follow the instructions included with the test.
• Check the expiration date before using the test.
• If your result is negative but your period still hasn’t started, test again in 48 to 72 hours.

Most home pregnancy tests are highly accurate when they’re used correctly and at the right time.

If you’re still unsure about your results, another pregnancy test and a follow-up appointment can help provide clarity.

A Positive Pregnancy Test Is Only the First Step

A pregnancy test can tell you that you’re pregnant, but it can’t tell you everything you need to know about your pregnancy.

That’s why an ultrasound is an important next step.

An ultrasound can determine:

• Whether the pregnancy is located inside the uterus.
• Whether the pregnancy appears to be developing.
• Approximately how far along you are.

This information is important for protecting your health.

For example, an ultrasound can identify an ectopic pregnancy, which occurs when a pregnancy develops outside the uterus. An ectopic pregnancy is a medical emergency that requires immediate treatment and cannot be treated with abortion drugs.

An ultrasound can also determine whether you’ve experienced a miscarriage, since pregnancy hormones may remain in your body for days or even weeks after a pregnancy has ended.

No matter what pregnancy option you’re considering, an ultrasound provides important medical information that can help you make an informed decision.
