Can an ultra sound give the wrong result about the baby gender after 29 weeks?

Yes, an ultrasound can occasionally provide incorrect results regarding the baby's gender, even after 29 weeks. Factors such as the baby's position, the technician's experience, and the quality of the imaging equipment can influence accuracy. While the chances of misidentification decrease as the pregnancy progresses, they are not eliminated entirely. Therefore, it's advisable to consider ultrasound results as one of several indicators rather than a definitive answer.
