Yesterday morning I had my usual ultrasound on Mr. Derrick. However, the tech decided to do a quick check on Derrick's growth and see where he was at weight wise. Please refer back to this post (click here!) to see what all the measurements mean and to compare to his measurements three weeks ago. When the ultrasound was done I was 34 weeks, 4 days along.
BPD (Biparietal diameter) : 8.65 cm which is the size of an average 34 week, 6 day fetus
HC (Head Circumference): 31.60 cm which is the size of an average 35 week, 3 day fetus.
AC (Abdominal Circumference): 29.58 cm which is the size of an average 33 week, 4 day fetus
FL (Femur Length): 6.89 cm which is the size of an average 35 week, 3 day fetus.
This puts Derrick at 5 pounds, 5 ounces! He is in the 40th percentile (42% to be exact) for his overall development.
This means that if you were to take 100 fetuses that were at 34 weeks, 4 days along and line them all up according to size Derrick would be number 42. So it's not necessarily a bad thing or means that he is behind. It just gives an idea of where he is compared to others.
Taking his weight from 3 weeks ago (3 lbs, 15 oz) and comparing it to now shows that he is right on track. Babies at this point are supposed to gain about a 1/2 a pound a week. So as long as he continues along this trend he will be between 6.5 and 7 pounds when he is born.
What is your guess on his weight and length at birth?
My official guess is 6 pounds, 9 ounces and 20.5 inches long!
