Can Having A Yeast Infection Affect A Pregnancy Test?

March 20, 2023 by Marjorie R. Rogers, MA (English), Certified Consultant

A yeast infection can potentially affect the results of a pregnancy test. If a woman has a va*ginal yeast infection when she takes a pregnancy test, the acidity in her vag*ina may alter the pH level of her urine and cause false negative or false positive results. For this reason, it is recommended that women wait to take a pregnancy test until at least one week after their last period.

There are a lot of old wives tales out there about how different things can affect a pregnancy test. Some people say that you can’t get pregnant if you have a yeast infection, but that’s not true. Yeast infections won’t affect your ability to get pregnant, but they can affect your pregnancy test results.

If you have a yeast infection when you take a pregnancy test, the test may come back positive even if you’re not actually pregnant. That’s because the presence of yeast can cause false positives on some pregnancy tests. So, if you think you might be pregnant and you have a yeast infection, it’s best to wait until the infection clears up before taking a pregnancy test.


First Signs of Pregnancy, Yeast Infection

If you think you might be pregnant, it’s important to know the early signs and symptoms. Many of these can be indicative of other conditions, but if you’re experiencing one or more of them, it’s worth taking a pregnancy test. One common early sign of pregnancy is a yeast infection.

This can cause itching, burning, and redness in the area. If you’ve never had a yeast infection before, or if you have any concerns, speak to your doctor. Other early signs of pregnancy include fatigue, nausea, breast tenderness, and mood swings.

Can You Take Pregnancy Test With Yeast Infection?

No, you cannot take a pregnancy test with a yeast infection. A pregnancy test is designed to detect the presence of the hormone human chorionic gonadotropin (hCG) in your urine, which is only present when you are pregnant. Yeast infections, on the other hand, are caused by an overgrowth of the Candida albicans fungus.

While both conditions can cause similar symptoms (such as itching, burning, and discharge), they are completely unrelated and require different treatment. If you think you might be pregnant, it’s important to see your doctor or take a home pregnancy test for an accurate diagnosis.

Can an Infection Mess With a Pregnancy Test?

If you think you might have an infection, it’s important to see a healthcare provider to get treated. Depending on the type of infection, it can sometimes affect your pregnancy test results. For example, if you have a urinary tract infection (UTI), it can causefalse-positive pregnancy test results.

This is because when bacteria from the UTI enters your urine, it can interfere with the hCG hormone that pregnancy tests look for. False-positive results are more likely with early pregnancy tests that are sensitive to lower levels of hCG. In rare cases, some infections can also cause false-negative results.

This is most likely to happen if you’re taking certain antibiotics for the infection. The antibiotics can temporarily lower your hCG levels and give you a false-negative result. If this happens, you should retest in a few days after finishing the antibiotic treatment.

Can a Yeast Infection Cause a False-Negative?

A yeast infection can cause a false-negative on a pregnancy test. This is because the yeast infection can interfere with the way the body breaks down and absorbs hCG, the hormone that is responsible for detecting pregnancy. While a false-negative is possible, it is rare and usually only occurs if the test is taken too early or if the person has a very high level of hCG in their system.

What Can Affect a Pregnancy Test?

A pregnancy test can be affected by a number of factors, including the time of day, the level of hCG in your body, and medications you are taking. If you take a pregnancy test too early in your cycle, it may not pick up on the hCG hormone that is released when you ovulate. This means that you could get a false negative result.

Similarly, if you take a pregnancy test later in your cycle (after you miss your period), there is a possibility that the levels of hCG in your body have not increased enough to trigger a positive result. Pregnancy tests are also designed to work best with morning urine, as this is when hCG levels are highest. Finally, certain medications can interfere with pregnancy tests and cause false results.

These include some fertility drugs (like clomiphene) and anti-nausea medications (like promethazine).


A woman’s body goes through many changes during pregnancy, and one of those changes is an increase in discharge. This increased discharge can sometimes cause a yeast infection, which is usually harmless. However, some women worry that a yeast infection could affect their pregnancy test results.

There is no need to worry about a yeast infection affecting your pregnancy test results. A yeast infection will not change the levels of hCG in your urine, so it will not affect the accuracy of the test.
