generally, there is not more risk in haveing a bub at 42 weeks than at 38. This is both what I have read, and what I've discussed with my midwife.

You can ask to have u/s to monitor placenta function and they should be able to provide that for you or refer you to have it done.

If you are wanting to try natural induction methods there's an article on the main BB site too.

ETA: DS was 10 days o/d. I did have an induction but i think the accupuncture and the stretch and sweep helped too.
