Approximately 6 million pregnancies occur in the United States every year, and though the majority of them result in live births, many pregnancies are lost every year. Overall, it is estimated that 2 million pregnancies are lost in the U.S. annually.

There are several different ways that women can lose a pregnancy. The majority of those pregnancies lost are due to terminations, which account for approximately 1.2 million lost pregnancies. Other possible ways of losing a pregnancy are through miscarriages, ectopic pregnancies, molar pregnancies and stillbirths.
