about a week before I delivered my daughter I had an ultrasound and they said she was 5 pounds. She was 7 pounds 1 oz when she was born. So unless she gained 2 pounds in a week, they were off lol
My brother was almost 11 pounds when he was born
My first daughter weighed 7lb at 34 weeks and was born 10lb at 38 weeks. But im a diabetic. Ultrasounds can be off. They thought she would only weigh about 8lb at birth and they were so wrong.
My son was 8.8 lbs when he was born the doctor told me he probably be over 9 and everything was good in my pregnancy. I think they can be off its not a real scale to calculate the weight. It's just an estimate
I think some of those ounces is also amniotic fluid but it sounds he/she is right on track!
My 2nd son was 10lbs 14oz but I had gestational diabetes. .was a rough pregnancy alot goin in and druing my ultrasound the tech said he wad like a 9lb bby but still had him natural but tore like crazy
