How accurate is weight measurement on U/S?

Question

Just had my 26 week check up and my
Baby was measuring in 24th percentile for weight, dr said was small weight wise, but has me coming back for recheck in 3 weeks to check growth. I’ve only gained 6 pounds entire pregnancy and dr mentioned that to me today but idk what else to do, I eat till I’m full, I eat what I want but I’m not gaining... she marked “insufficient maternal and fetal weight gain” on my reason for recheck.. if I force anymore food down my throat it would make me sick.. but honestly how accurate are the weight measurements?

Answer

Not very. They can off by a few lbs depending on the time they’re taken. They told me my baby would be around 8lbs, she was born barely 6lbs.

Answer

My dr said the further along you get the less accurate the ultrasound is for weight.

Answer

They can be off by 2 pounds but usually they measure baby to be bigger when the baby’s actually smaller .. meaning your baby can be 2 pounds lighter still. Have you looked into taking ensure ? Or other pregnancy safe drinks like that to help you gain weight ?

Answer

I wouldn’t worry about weight gain if you’re eating. I gained 8 lbs total and was small to begin with. I barely had a belly when I delivered. He was born two weeks early and 7 lbs 14 oz and 21 1/4 inches

Answer

They said my baby was going to be 10+lbs.  he was 8.8 lbs.

Answer

It's very rare for them to be off by a few pounds but a pound they can be I mean if you Dr is saying she's low then it's most probably right they check it off your BMI too

Answer

With my 3rd baby they were only a few oz off. My 4th baby they were almost 2 lbs off

Answer

They said my baby was gonna be 7lb 4oz she was. Almost 9lb
