Help me check if the BC data is normal?

Patient's question:

This is the ultrasound data from my 26 weeks + 6 days of pregnancy. Please help check if it is normal.
Biparietal diameter (BPD): 63 mm Head circumference (HC): 233 mm Femur length (FL): 50 mm
Abdominal circumference (AC): 218 mm Placenta attached to the right posterior wall Thickness: 34 mm Maturity: Grade I+
Lower margin distance from internal cervical os: >50 mm Fetal heart rate (FHR): 155 beats/min Amniotic fluid: 53 mm
Umbilical vessels: 3 roots
U-shaped notch seen at the nuchal region (Does it indicate a nuchal cord? If so, is it normal at this stage of pregnancy?)

Doctor's answer:

Hello, according to your examination results, the U-shaped notch seen on the side of the neck could be due to the umbilical cord around the neck, but the fetus may be able to loosen it on its own. The rest should be fine. You just need to wait and see, and have regular prenatal check-ups.
