35 in 10,000 is 0.35%, or a 1 in 286 chance of stillbirth.
Indeed, and it's worth highlighting the word stillbirth.
That statistic doesn't include the women who nearly died, or the babies who suffered life changing birth injuries.
I'm honestly shocked at how sanguine some posters are about the risks of over going over term.
The placenta has a shelf life and it's already deteriorating towards the end of a normal gestation because it's theoretically done it's job.
What's especially sad is that it's perfectly possible to feel fine and not understand that deterioration because in the U.K. it's not routinely screened for.
Personally I would not go over 40 weeks, though that decision was never enacted in my case as I went into labour at 37 weeks (but 38 by my calculation).
All the best to you OP and I wish you well, but I hope you take on board the information you've been given here about the risks.
