Pregnancy tests detect a hormone called human chorionic gonadotropin (hCG), which begins to increase after pregnancy begins. While most tests are highly accurate when used correctly, factors such as timing can affect the result. Knowing when to test and how pregnancy tests work can help you better understand your results and decide whether additional testing may be needed.

hCG Detection
Pregnancy tests detect the presence of a hormone known as hCG in your body. This hormone is produced once a fertilized egg implants in the uterus, about 6 to 10 days after conception. The amount of hCG in your body can vary depending on when you ovulated and how early you take the test, so levels aren’t the same for everyone.
While some tests claim to detect pregnancy up to six days before your missed period, early testing is less accurate. It takes time for hCG to reach detectable levels, and an early test may yield a false-negative result.
When to Test
If you have regular cycles, the FDA recommends testing one to two weeks after you miss your period for the most accurate results.
Testing early in the day may improve accuracy because pregnancy hormone levels are often easier to detect in the morning. It can also help to avoid drinking large amounts of fluid immediately before taking the test.
Understanding Results
A negative test before a missed period does not always rule out pregnancy. If your period has not started, consider testing again after a few days, as pregnancy hormone levels rise over time.
If your period is still late and tests remain negative, a healthcare provider can help look into other possible causes.
A false positive is rare, but it can happen. This may occur after an early pregnancy loss, sometimes called a chemical pregnancy, when hCG is still present in the body for a short time. Certain medications that contain hCG, as well as hormonal changes related to ovarian conditions or perimenopause, can also affect results.
