How Pregnancy Tests Work: What You Need to Know

When unsure whether you’re pregnant, taking a pregnancy test is often the first step toward finding answers. Many begin with an at-home test, but confirming that result with a lab-quality test is essential for gaining clarity and planning your next steps.

Pregnancy tests work by detecting a hormone called human chorionic gonadotropin (hCG). This hormone starts to build in your body soon after a fertilized egg implants in the uterine lining and the placenta begins to form.

A positive test indicates that your hCG levels are high enough to be detectable, indicating a pregnancy.

When Should I Take a Pregnancy Test?

Most people take a test after noticing early symptoms, like a missed period, nausea, or sore breasts. These signs can suggest a pregnancy, but other factors, like stress or health conditions, can cause similar symptoms.

According to the Mayo Clinic, the best time to take a test is at least one to two days after your missed period. This allows time for hCG to build up to a detectable level in your body. Testing first thing in the morning, when your urine is most concentrated, can also improve the test’s accuracy.

What If the Test Is Positive?

If your result comes back negative but you still suspect you might be pregnant, it may simply be too early to detect hCG. Try testing again in a few days, and follow all instructions carefully.

If your test is positive, it’s crucial to gather more information. That’s where Choices Pregnancy Center can help. We offer self-administered pregnancy tests in a confidential environment.

You may be eligible for an ultrasound if your pregnancy test is positive or if you have prior proof of pregnancy. This scan helps determine vital details such as how far along you are and whether the pregnancy is progressing in the right location.
