Can Birth Control Cause A False-Positive Pregnancy Test


Can Birth Control Cause A False-Positive Pregnancy Test?

When trying to determine if you are pregnant, taking a pregnancy test is one of the most common methods for doing so. However, in some cases, birth control can cause a false-positive result on a pregnancy test.

What Causes A False Positive Pregnancy Test?

There are a few reasons why a pregnancy test may give a false positive result, even if you are not pregnant. Here are some of the most common:

  • Hormonal Imbalance: Hormonal changes in the body can cause a false-positive result on a pregnancy test. This can happen if you are on birth control pills or have recently changed your hormonal contraception. This can also be an issue if you have recently had a miscarriage, if you have recently stopped taking hormonal contraception, or if you are going through menopause.
  • Medications: Certain medications, such as antipsychotics, HIV/AIDs medications, diuretics, and anti-convulsants can cause a false-positive result on a pregnancy test.


  • Expired Tests: Using an expired pregnancy test can also give a false-positive result, as the sensitivity and accuracy of the test may have decreased over time.

Can Birth Control Cause A False Positive Pregnancy Test?

Yes, birth control can cause a false-positive result on a pregnancy test. This is because hormonal contraception can cause an increase in the levels of the pregnancy hormone, human chorionic gonadotropin (hCG), in the body. As a result, this can cause the test to give a positive result, when in fact, you are not pregnant.

What Should You Do If You Receive A False Positive Result?

If you receive a false positive result from a pregnancy test, it is important to speak to your doctor. They will be able to confirm the result with a blood test and advise you about your next steps. In some cases, if the test was caused by taking hormonal contraception, your doctor may recommend changing your method of contraception, or taking a different type of birth control.

In conclusion, while it is rare, it is possible for birth control to cause a false-positive pregnancy test. It is important to speak to your doctor if you receive such a result and they will be able to help you to determine the cause and next steps, if necessary.

Can I get a false-positive pregnancy test result if I’m on birth control?

Yes, it is possible to get a false-positive pregnancy test result if you are on birth control, though it is uncommon. False positives can occur in rare cases, due to other hormones present in the body or contaminated test kits.
