A false-positive pregnancy test can be devastating—especially for women who have difficulty conceiving or who are actively trying to get pregnant. Thankfully, false-positive pregnancy tests are rare, but they can happen. Here are some of the most common causes of a false-positive pregnancy test. At-home pregnancy tests check for the hormone hCG. Right after a fertilized egg attaches to the uterine lining, the placenta then forms and it produces hCG, according to the Mayo Clinic. A blood test can detect hCG about 11 days after conception, and a urine test can detect it 12 to 14 days after conception, according to the American Pregnancy Association.
However, if you are having your period and got a positive result, you should definitely see your medical practitioner. A urine pregnancy test looks for a hormone called Human Chorionic Gonadotropin HCG that is found in the urine during pregnancy. Having your period during the test should not interfere with the accuracy of these results. Within about 2 weeks after conception, there is enough of this hormone to show up in the urine. Also, when conception occurs, this signals other hormone changes to happen to stop the period from happening, because the lining that is shed during the period helps nourish the baby that is growing the uterus.
Missing a period is one of the first signs that you might be pregnant. You may take a home pregnancy test as soon as possible. If you have very early pregnancy symptoms, such as implantation bleeding , you may even take a home pregnancy test before your first missed period. Some pregnancy tests are more sensitive than others and can accurately detect a pregnancy several days before a missed period. But after taking a home test, your excitement may turn to confusion as you notice a faint positive line.
You may have experienced what some doctors call a chemical pregnancy, or a very early pregnancy loss, which is believed to account for up to 75 percent of all miscarriages. In fact, there's actually a silver lining. However, for some reason implantation never fully happens — and an ultrasound won't detect a gestational sac or placenta developing — resulting in bleeding around a week after your regular period was due. So if you have heavy bleeding with or without cramping after a positive pregnancy test, call your doctor right away, as you may be experiencing a chemical pregnancy. At the time of conception, an egg and a sperm combine chromosomes 23 from each partner to form a zygote, which begins to grow through rapid cell division.

A chemical pregnancy is an early pregnancy loss that occurs shortly after implantation. Chemical pregnancies may account for 50 to 75 percent of all miscarriages.
