When should the first ultrasound be done?

A mother-to-be should get her first ultrasound during the midpoint of her pregnancy, around 18 and 20 weeks. Waiting until this time frame enables her to learn the child's sex.

Moms-to-be don't have to necessarily wait until the second trimester. They can get this important diagnostic test, also known as a sonogram, done during the first trimester. An ultrasound at 6 to 10 weeks is useful for confirming the pregnancy and the due date. Moreover, the American Pregnancy Association reports that a first trimester screening is the most accurate, noninvasive way to test for fetal malformations, such as Down syndrome.
