Im going for one at 17wks and 30wks
If you are juss lookin' to find out the sex, then you can get It done as early as 15-16 weeks.
After 32 weeks, there Is less fluid around the baby to work with, which can lead to suboptimal results. Also, after 32 weeks, the baby may have already descended Into the pelvis, making getting any view of the baby Impossible.To get good pictures, 3D ultrasounds are best performed between 20 and 32 weeks, and the best pictures are between 24 and 30 weeks. If you would like to get a closeup shot of the face, then 28 to 32 weeks Is the best time
