Patient's question:
No.Doctor's answer:
BPD represents the biparietal diameter, which refers to the measurement of the diameter on both sides of the fetal head. It is also one of the indicators for estimating the size of the fetus. According to general patterns, at 3 months of pregnancy, the BPD is usually less than 3 centimeters. After 5 months of pregnancy, it generally corresponds to the gestational month. For example, at 28 weeks (7 months), the BPD is approximately 7 centimeters, and at 32 weeks (8 months), it is about 8 centimeters, and so on. After 8 months of pregnancy, an average growth of about 0.2 centimeters per week is considered normal.
