I'm a little perturbed with my doctors. My weekly appointments seem to be rush in/rush out and not very comprehensive. When I asked my Dr. last week how big the baby is, she flatly replied that most babies are around 5 lbs at this point (I was 36 weeks). I went again at 37 weeks and another doctor measured with his hands and told me about 7 lbs. That's quite a difference! Isn't the only real way to tell via ultrasound? They also don't want to check my cervix unless I'm having contractions so they don't irritate it. I'm bummed.
Re: how big is she??
u/s is the most accurate way to check weight, but even that can be off by as much as 2 lbs either direction. it's all a guess. and honestly, unless they think the baby is dangerously large or small, is doesn't matter. if you are on track they are happy.
and a lot of docs don't do internals until 38 weeks or signs of labor have begun.
in the end, though, if you are concerns and have a question, demand an answer. it might not be the one you want, but your doc is there to give you the info you want/need.
