So at my 28 week appt my doc said I was measuring big didnt say much else except we would see what my 1 hr test for gd says well I failed it but just barely and I did the 3 hr test which I passed, she then gave me an ultrasound at 30 weeks and my lil boy is measuring a lil over 4 pounds already! she said if I keep up with the normal rate that babies tend to grow he would be 9/9.5 pounds by birth so she wants me to follow the gd diet as much as I can to try and prevent that. I have heard that the farther along you get the less accurate they are. It was fun to see my lil man again. Here is a pic of his lil face. I am getting a 3D/4D one next thurs cant wait to really get a look at what he will look like!

Yes they can be off. My second was my only one I had at 22 week ultrasound. With there judgement in her size then, how I was showing, possible GD(which I had no clue she put that down. Since I passed the test), since I as always 4 cm bigger each time. I was told I would have a 9-10lb baby. Well she was 6lbs 3oz and 18.5".

Aww!  I got to see my little girl's face this week (she was 90% sure it's a girl, but I find out Fri. for sure). 

Sorry about my post, but idk much about GD.  I'm on the 'worry if it happens' mode.  I'd feel good about passing the 3 hour though.

Yep, the farther along then less accurate is true.  I had an ultrasound once at  32/34 weeks or so...I forget exactly, and the tech said that he is given a 4-6 week error margin.

Ultraosunds aren't accurate for guessing a baby's weight after the first trimester. There are too many variables in the estimates to really know for sure.

Sono's are super inaccurate for weight judgement. Once in a while you get a tech that is oober good and hits it right on the nail (I had one that hit it dead on!). I wouldn't stress it. 
Also, if they are starting in on the "big baby" thing now, watch it! They tend to like to use that as an excuse to induce early or do c-sections. Don't sign any papers for that unless there is an actual medical reason. They did that crap to me and I wish I had been a little more educated at the time about it. Gotta love the convenience factor.

I really dont think he will be as big as they say..dunno if it has any factor but my hubby and I were both smaller babies like 7 to 7.5 range so thats what Im guessing. At 20 weeks he was 13 oz so just shy of one pound so they are saying in 10 weeks he has gained like 3.5 pounds that seems excessive to me. My OB said she wont induce on weight even if he gets that big but to me it sounds like it could be a higher chance for c section. I guess we shall see!

Thanks ladies for all your comments! I wish they would have told me there could have been room for errors on weight both the tech and my OB seemed confident thats how much he is weighing in at. Im trying not to stress about it this is my first baby and a miracle to even be pregnant so I wanna enjoy what little time I have left. It sucks to have to try and eat diabetically my OB told me that I can have 3 tbs of carbs at any given meal..soo gonna be difficult considering Im a carb lover but will do what I can since this adventure is almost over.

I honestly wouldn't worry about it too much. Not unless you are eating really poorly and really putting on the weight yourself. Some women just have bigger babies. No big deal. And like you said, ultrasounds can be off.

My first was 9lbs 10.8oz. I had no problem at all birthing her.

my son (that is due at anytime now) was considered to be HUGE until my last ultrasound a at 34 weeks.. they now say he is completely under weight.. idk what to think

Yeah, they can be soo wrong. My second baby was supposed to be 10lbs at 38 weeks and they pushed and pushed for an induction. Waited until she was ready anyway and she came at 8lbs 9oz, birthed her naturally just fine :)
