Does Breastfeeding Affect Pregnancy Test Results?

When you’re breastfeeding, it’s totally normal to worry about whether you can still get pregnant. And, if you are pregnant, can breastfeeding cause a false positive on a pregnancy test? The answer is no.

does breastfeeding affect pregnancy test results

Fertility and breastfeeding go hand in hand for many women. It’s not unusual for nursing moms to get pregnant again while they’re still breastfeeding. In fact, statistics show that about 75% of women who are exclusively breastfeeding will get pregnant within the first year of their baby’s life.

If you’re taking a pregnancy test and you’re worried that breast milk might give you a false positive result, don’t be. Pregnancy tests are very accurate and breast milk will not affect the results.

How Breastfeeding Does Not Affect Pregnancy Tests?

When you find out you are pregnant, one of the first things you want to do is take a pregnancy test. You may be wondering if breastfeeding will affect the results of the test. Breastfeeding will not affect the results of a pregnancy test.

Pregnancy tests look for a special hormone called human chorionic gonadotropin (hCG). This hormone is produced by the placenta and can be detected in urine or blood. hCG levels increase as the pregnancy progresses.

If you are breastfeeding, your body will continue to produce hCG even after you have given birth. This is because hCG helps to maintain milk production. The levels of hCG in your body will slowly decrease over time, but they will not be affected by breastfeeding.

So, if you are breastfeeding and take a pregnancy test, the results will be accurate.

Does Breastfeeding Change a Woman’s Hormone Levels?

The act of breastfeeding alters a woman’s hormone levels in order to produce milk for her child. Levels of the hormone prolactin increase, while levels of estrogen and progesterone decrease. These hormonal changes encourage the body to release milk and help to maintain the production of milk.

How Do Pregnancy Tests Work?

When a woman suspects she may be pregnant, one of the first things she’ll do is take a pregnancy test. But how do these tests work?

Pregnancy tests work by detecting the hormone human chorionic gonadotropin (hCG) in a woman’s urine. This hormone is only produced when a woman is pregnant. The test detects the presence of hCG by looking for a specific reaction between the hCG and antibodies in the test strip.

Most pregnancy tests are designed to detect levels of hCG as low as 25 mIU/ml, which is generally considered to be within the “early positive” range. Some tests are even sensitive enough to detect levels as low as 5 mIU/ml.

Accuracy of Home Pregnancy Tests when Breastfeeding

There is a lot of concern among breastfeeding mothers about the accuracy of home pregnancy tests while breastfeeding. The concern is that the test may give a false positive reading and that this could lead to the mother unnecessarily stopping breastfeeding.

However, there is no evidence to suggest that home pregnancy tests are any less accurate when a woman is breastfeeding than when she is not. In fact, a study published found that the accuracy of home pregnancy tests was not affected by whether or not the women were breastfeeding.

So if you are concerned about whether or not you are pregnant and you are breastfeeding, don’t be – go ahead and take a home pregnancy test! And remember, if the results are positive, it’s important to speak to your health care provider to determine next steps.

Is It Safe to Breastfeeding While Pregnant?

There is no evidence that breastfeeding while pregnant harms the baby. In fact, some benefits of breastfeeding may even extend to the baby if done while pregnant.

In fact, breastfeeding can even provide some health benefits for the mother and child during pregnancy. For example, breastfeeding can help to reduce the risk of preeclampsia and other health problems in the mother. It can also help to boost the baby’s immune system and protect them from infections. Breastfeeding during pregnancy is also a good way to increase the mother’s milk supply after the baby is born.


In conclusion, breastfeeding does not affect pregnancy test results. While some women may feel like their results are inaccurate, this is not usually the case. Pregnancy tests are very reliable and breastfeeding will not impact the results.
