The Hormone Behind the Result

Pregnancy tests detect a hormone called human chorionic gonadotropin, or hCG. Your body begins producing hCG after a fertilized egg implants in the uterus. This does not happen immediately after sex. Implantation typically occurs about 6 to 10 days later, and hCG levels rise gradually from there.

Because hCG builds over time, testing too early can lead to a result that is not accurate. Waiting until at least a day or two after a missed period usually increases the likelihood of a reliable answer.

False Negatives and False Positives

Although pregnancy tests are generally accurate, false results can happen.

A false negative occurs when the test says you are not pregnant, but you actually are. This most often happens when you test too early, and hCG levels are still too low to detect. Diluted urine or not following instructions carefully can also affect the result.

A false positive is less common but still possible. This can happen after a very early pregnancy loss, sometimes called a chemical pregnancy, when hCG remains in your body for a short time. Certain medications containing hCG, ovarian conditions creating hormonal changes, and even menopause or perimenopause may also influence results.

If you receive a confusing result, professional testing can help eliminate guesswork.

Why Medical-Grade Testing Matters

At New Beginnings, we provide free medical-grade pregnancy tests administered in a supportive setting. This type of testing offers greater reliability than many over-the-counter options and lets you ask questions right away.

If your test is positive, you may qualify for a limited ultrasound. An ultrasound can confirm whether the pregnancy is located in the uterus, estimate how far along you are, and check if the pregnancy appears to be developing. These details are important for protecting your health and understanding your options.

You Don’t Have to Figure This Out Alone

Waiting for results can bring a mix of emotions. Whether you are hoping for one outcome or another, you deserve accurate information and support.
