A nonstress test is a noninvasive test that poses no physical risks for you or your baby.

While a nonstress test can offer reassurance about your baby's health, it can cause anxiety. A nonstress test also might not detect an existing problem or might suggest that a problem exists when there is none.

Also, keep in mind that while a nonstress test is often recommended for women who have an increased risk of pregnancy loss, it's not always clear if the test is helpful.
