Ultrasound Vs Measurement???

Unfortunately, I am getting late prenatal care due to being out of the country for a while, and couldn't get medical. My ultrasound report says that the "measurements result in a sonographic estimated gestational age of 28 weeks and 2 days consistant with an EDD of 9/27/11 and concurrent with clinical history" "Estimated fetal gestational weight is 1188 gm." But at the top of the page it says, "Clinical Information: Size larger than dates". I saw my OBGYN today for the first time, and he measured my tummy and said I measure at 32 weeks. Which would be the most accurate? And could my OBGYN be wrong? I go next to see him next week, but this is bugging me. I also went in for the Glucose test also today, and waiting for those results as well. If I have diabetes, could that be why he measured me at 32 weeks when the Ultrasound said 28 weeks??

  • Ultrasound is sometimes better but its better to go off your LMP. With my son they said I was measuring 12 weeks when I knew I was 8 weeks since I wasn't having sex before then. (got pregnant first day my husband was back from deployment) My stomach measured 32 weeks when I was 26 weeks.

  • I told the doctor when my LMP was, and haven't bled after that. He said sometimes women think its a period when it's really not. But I bled the same and I always clot - I know, tmi sorry. :( Could he be wrong?

  • Go with what you feel is right. Doctors are wrong a lot. Its your body. If you know it was your period then it was. He's not you and doesnt know what your body is like. I would suggest seeing another doctor if he's telling you you're wrong about your own body and period.

  • at 31 weeks my doctor measured 28cm, but my baby was at the 29 4days , so its all different

  • Your lmp is usually most accurate, followed by ultrasound, and then by measuring size. I have always measured quite big, but my largest baby was 8 lbs 9 oz. But if you have gestational diabetes (I did), then yes it can result in a larger baby particularly if it's not well controlled.

  • just be careful because my doctor done the very samething to me and his wrong dates lead up to my son being born to soon and was pre_mi and had to stay in the nicu for three weeks i would say if you know your dates are more accurate than go with your dates ........
