What is the normal weight of a 25 week fetus?

Question
Hello doctor, I am 25 weeks and 1 day pregnant. I had a 4D ultrasound, the results were as follows: Fetal weight 776 g, Head circumference: 220, Abdomen: 217, Biparietal diameter: 58, Diameter across abdomen: 64, Length of femur: 42, pregnancy is in the 39th percentile compared to the 25th percentile, BPD is in the 6th percentile, HC is in the 5th percentile.
Did the doctor ask if the baby's results and weight are satisfactory? The sonographer only said the baby's head was a bit small, the other parameters were normal. But I'm still very worried and hope the doctor can help me.
Thank you doctor very much!

Hi, the ultrasound index with 25 weeks 1 day pregnancy is so about growth. Regarding the index of biparietal diameter and head circumference, it is still above the 5th percentile line, ie in the normal group, besides the organs inside the skull that have not been found abnormal, you do not need to worry. You just need to periodically monitor your pregnancy by appointment, follow your doctor's instructions and provide adequate nutrition for you and your baby.
Thank you for your question to Vinmec Health System. Best regards.
