Pregnancy tests work by checking your urine (pee) for a hormone called human chorionic gonadotropin (HCG). Your body only makes this hormone if you’re pregnant. HCG is released when a fertilized egg attaches to the lining of your uterus — when pregnancy begins. Pregnancy tests work by detecting the hCG hormone in your urine. When your urine comes in contact with the specially treated strip on a pregnancy test stick, results appear within minutes, indicating whether or not hCG, the pregnancy hormone, has been detected.
How soon will a pregnancy test read positive?
In many cases, you might get a positive from an at-home test as early as 10 days after conception. For a more accurate result, wait until after you’ve missed your period to take a test. Remember, if you take a test too soon it could be negative even if you are pregnant.
