Don't stress, my son was measuring 39 weeks at 34 weeks, they told me if he stayed in full term I was gonna deliver a 10lb baby. Boy, they were off. 7lbs 7ounces at 38 weeks! The ultrasound is just a guess, also something my ultrasound tech told me, between 34 and 36 weeks, there is a growth spurt, it's the last growth surpt, depending on when the spurt happens and when the ultrasound happens it can throw the information wayyyyyy off, making the baby seem bigger, but it reality since they hit that growth spurt, they may not get much bigger. My son was also 6lbs, 6ounces at 34 weeks, he only gained 1lb before birth.

@tiera_shaye they think I'm farther along and I can go anyway.
@threeplusone I usually have big babies but he is really big

Don't worry too much. Ultrasounds aren't always accurate this late in pregnancy. Mine were off but in my case my kids were bigger than what they thought lol. Unless you've had big babies before or have GD now don't stress about it.

Oh my! So are they changing his due date then? Do they think you are actually farther along or he is just a big baby?
