Please some input; Fetal weight accuracy by u/s at term

[kris777]

I am 39w5d and I had an u/s last night so my doctor could check fetal weight because he might induce me this week.  The tech told me the baby measured to be 9 lbs, but that it could go 2 lbs in either direction?!!!!  I am freaked thinking he might be bigger than that...........my first son was term also and he was 7lb 4oz so I figured this baby would be about the same.  I am waiting to talk to my doc this morning to see what he wants to do and I am sooo anxious!

Does anyone have any input on how accurate you think this might be??  I thought it could go only one pound in either direction?  Thanks!!!

I agree with grandmatobe My youngest son was estimated at 6lbs 4ounces at the time of labor, 20 min later when I actually gave birth he was 9lbs 6ounces.

My sister just had the samething done with her, he baby was estimated at 8lbs 6ounces and she had a 10lbs 1.2 ounce baby the day after her due date when she was induced.

I dont think they are very acurate, they do measurements, but who is to say your baby isn't short or something. I always have short babies under 22 inches long, and they always estimated them to be about 6 to 7 pounds and they all came out over 9 pounds.

They told my daughter that her baby was 8 1/2 pounds, so they induced.  She ended up being 6 lb 13 oz.  They aren't accurate at all....IMHO.

My sister had an u/s at 38 weeks and they said that she was going to have an 8-9 pound baby. He ended up being born that week and weighed 5lbs. 12oz.! I think that the weight gets more and more inaccuate the bigger your baby gets. I think its just harder to get the measurements when the baby is all crammed up in there. LOL. Good Luck!

with my second2 days befor her due date they told me she was about 11lb she was born the day after her due date at 10lb so the can be off try not to worry

Thanks...........I am so anxious now because I never thought I would have a big baby or one over 8 lbs.  I guess I will be finding out very soon either way!!

I am definitely NO expert, but they told my best friend her son was only looking like he was 7 lbs. (he was 10 days overdue at the time) He ended up being almost 10 pounds.. I think that they can be WAY off.. But I only have that 1 experience so what do I know? =)

GOOD LUCK and keep us posted!
