Ultrasound shows no legs could it be wrong?

Yes, it is possible for an ultrasound to yield incorrect results, including the absence of legs in a developing fetus. Factors such as the position of the fetus, the quality of the ultrasound equipment, and the technician's experience can influence the accuracy of the imaging. If there are concerns about the results, a follow-up ultrasound or additional imaging techniques may be recommended for confirmation. Always consult with a healthcare professional for the most accurate interpretation of ultrasound findings.
