We were supposed to find out the gender of LO at our ultrasound on Thurs. Unfortunately, baby was uncooperative. The tech said that we could ask the doc to request another ultrasound to try again later, but a friend suggested a 3D ultrasound. She said that the brochure she'd gotten from the 3D Ultrasound clinic this week said that 3D ultrasounds had 100% gender accuracy. Anyone know if this is the case? I just don't understand how that can be true if the baby is uncooperative and in a poor position on the day of the ultrasound, 3D or otherwise.
