Why would you be induced before 40 weeks?
I would hang on for as long as you possibly can - book the induction for 41+4 or 5 if you can!
I was induced at 40+0 with my eldest (due to low amniotic fluid levels). It was fine, but I think early induction is almost inevitable going to take quite a long time, you are likely to be on your back and need monitoring, you are likely to get v tired, all of which means you are likely to end up with quite a medicalised birth (I had an epidural and forceps).
Not that there is anything wrong with this - I had quite a good experience.
But my second baby was much more straightforward and quick, he came in his own time at 40+10 - established labour at 9pm and I spent most of it in a good position in the pool, he was born at 4am. With my eldest they started the induction on the Sunday morning and she wasn't born till the Tuesday morning!
I would delay induction for as long as you can - often if you say you will come in for daily monitoring they will be happy with this. Trying to induce before 40 weeks, if there is no medical reason, sounds mad to me.
