Twice is usual: The most important pregnancy us is the fetal anatomy screen, at 18 to 22 weeks gestation. If there are any questions about dating, the most accurate us for delivery date is between 8 and 13 weeks. Your ob/gyn may also order an us to look for interval growth, or if you have some concerns or problems. Us is very safe, but 3d and color doppler ultrasound should be used only when necessary.
