Confused by ultrasound

Question

Sooo I got an ultrasound done on Thursday and I was 15wks1day according to my LMP. The nurse said I'm due july 4th. But said the baby was about 5ozs. I looked online and in baby books. He or she should only be about half that 2.5ozs. So now I'm thinking I'm further along? But it doesn't match up with my period date.. could she be that off based on the ultrasound? Or was she just giving me a random number? She measured the thigh bone head and belly but didn't give me those numbers... figured those helped her figure out the weight.

if your due date hasnt changed i wouldnt worry about it too much, im due just after you on the 7th and weight was never mentioned at my scans so far (although i dont think they bother about that in the uk unless they think the baby is particulary large at the end of a pregnancy) you'll notice some recent posts about weights being wildly inaccurate, and my first baby was deemed "huge" and i was sent to a different hospital 2 hours away to give birth...my "huge" baby was 8lb3oz (not little, but certainly not what i was told to expect!) my friend has also just given birth to her "huge" baby who was just 7lb 10!! dont worry too much about it if your due date hasnt moved, length measurements are much more accurate than weight meaaurements.

women could still have there periods when they are pregnant! they go by your first day of your last period... so you may be farther along then you think

I was measured at 6 wks, 12 wks and 18wks. I know that she did the measurments on the program and the program figured out how old the baby was. I'm actually measuring a week earlier according to the last round of measurements. I would just ask the dr at your next appointment. they get sent all your measurments so they will know.

That's strange. I also got an ultrasound on Thursday and I was 15w3d (yayyy July babies :) anyhow if your DOCTOR didn't give u a weight, I wouldn't pay attention. My doc doesn't even start measuring that stuff till about 20w or so.
