Re: Some advice would be great.
There's nothing quite like going into labor on your own!
That said, incidentally I had a 6.5 pound baby that they took at almost 37 weeks, was told repeatedly if I went to full term that I would have a BIG baby. Decided to go UP/UC with my youngest, carried him to almost 41 weeks, and he was 8 pounds even.
They just don't always know what they're talking about!
Even if you do end up with a bigger baby, I've heard for some they are easier to deliver, rather then harder, and chances are your body is quite capable, as long as you aren't tied to a bed on your back!
