Patient's question:
I did an ultrasound on November 30th. The BPD was 8.01 cm, GA was 32W1d, HC was 23.40 cm, EFW was 1125g, GA was 25W3d, biparietal diameter 80mm, head circumference 292mm, and femur length 62mm. I don't understand.Can you help me estimate how many weeks pregnant I am based on these parameters? Thank you.
Doctor's answer:
Generally speaking, the time of pregnancy is calculated from the first day of the last menstrual period. From that point, the duration is the pregnancy duration.Advice: Generally, calculating from the first day of the last menstrual period, the development of the fertilized egg to the number of weeks or the extent of its development has a scientific basis. However, it is only a reference data for clinical use and allows for some margin of error. Wishing you good health.
