Ds1 was born at almost exactly 42 weeks (half an hour before midnight, so not quite a full 42). I always thought his due date was off because it was based on LMP and my cycles are always long. But, he had a little bit of wrinkling on his ankles and wrists, and I remember my doc saying something about some calcification on the placenta. So, who knows. He was perfectly healthy, however, and his birth was really fast for a first birth.
Ds2 was born at 41 weeks 5 days. I was charting, so my date was accurate. He was covered in vernix, and looked term, not overdue at all. His placenta was perfect. This birth was even faster.
And both babies were right around 8 pounds, so not huge.
Can you get a copy of Henci Goer's The Thinking Woman's Guide to a Better Birth? There is a whole section that goes over postdates babies, and analyzes the research behind standard induction policies at 41+ weeks. Understanding why the docs recommended induction, and knowing logically why I did not agree with that analysis, based on the research helped me be really confident in refusing induction with my oldest. I was going to refuse after 42 weeks as well, so long as NSTs and ultrasounds showed baby was healthy.
I know a handful of homebirthing women who have gone to 43 weeks with healthy babies.
