Your baby starts looking like a baby at around 17 weeks, and so it is actually not recommended to get a 3D ultrasound before 17 weeks. The ideal time to get the best pictures is 24 to 30 weeks. After 32 weeks, some babies have already descended into the pelvis and so it may become impossible to get pictures after that point.
If you are overweight, you should come later, from 28 to 30 weeks. And if you have twins, then it is best to come earlier, from 22 to 28 weeks.
