Is a large biparietal diameter difficult to engage in the pelvis?

Patient's question:

No

Doctor's answer:

Okay, here is the translation following your instructions:
This single check item alone cannot determine if the fetus is abnormal. It should be analyzed comprehensively by combining other tests. Furthermore, fetal development is greatly related to irregular menstrual cycles and the timing of implantation. If the fetus is developing normally, you don't need to worry too much. Please have regular prenatal check-ups and monitor the situation dynamically.
