Ask your doctor: The ultrasound machine will have generated an estimated fetal weight based on these measurements. Your doctor should have that report. That said, this is typically quite inaccurate as it is only within +/- a pound. So a "6 pd" baby on ultrasound can weigh anywhere from 5-7 pounds at birth!
