Hmm sonographer or gynae will know best how to look at the ultrasound unless you also have experienced in this field. So should trust his expertise first. Usually if is legs right, such as bone it will appear whiter or brighter than the other stuffs in the ultrasound. But if you don’t quite believe can always ask for 2nd opinion. Since 20th week for me after knowing the gender, each scan I double check with the doc again of the gender in case that time baby didn’t show properly.
