A multiple pregnancy is when a woman is pregnant with two or more fetuses. Twins are the most common type of multiple pregnancy. So-called “higher-order” pregnancies (when a woman is carrying triplets, quadruplets, quintuplets, or more) are less common.
The risk for certain complications during and after pregnancy is higher in multiple pregnancies. To lessen these risks your doctor will see you more often than a woman carrying one baby.
