Going to have a 4D color ultrasound soon, do I still need a B?

Patient's question:

No

Doctor's answer:

Regarding the relevant issues of undergoing a B examination during pregnancy. According to your description, it is not necessary to immediately undergo a B examination. As long as fetal movement is normal and the fetal heart rate is normal during the obstetric examination, there is no need for another B. If the doctor recommends another B, it can also be done, and it will not affect the fetus.
