B gestational age and actual gestational age do not match, which one should be used as a reference, Director Guo?

Patient's question:

No

Doctor's answer:

Hello, it is normal for the theoretical gestational age to be inconsistent with the ultrasound gestational age because the growth and development speed of the fetus varies. Some fetuses grow a bit faster, while others may grow slower. Recommendation: In this case, it is best to use the gestational age shown by the actual ultrasound examination.
