How many months of pregnancy is good to do 4D ultrasound?

Patient's question:

No

Doctor's answer:

Hello, it is best to have a 4D color ultrasound at 4 months of pregnancy. At this time, the fetus is fully developed, there is more amniotic fluid, and it is easier to display the various parts of the fetus. Maintain a good mentality, have a reasonable diet, engage in appropriate exercise, and have regular prenatal examinations.
