You could always consider a stretch and sweep (if all is well and favourable) around 38 weeks then stay close the hospital for the following few days, if that's possible.

I went into spontaneous labour with both my girls but I did have a S&S with DD2 and my waters broke 3 days later. It was 1pm and she was born after just 37mins of active labour, which didn't start until almost 4pm.

I've now had two fast births and my OB expressed concern the day after DD2 was born about how fast a third labour would be. At my 6 week checkup, he told me he'd suggest induction with a third baby but just breaking my waters, nothing else. I honestly think I'd agree to it. The thought of giving birth at home, in the car or the car park does not interest me at all. It scares the day lights out of me to be honest! But I'm not interested in a full induction either, especially as both my girls have arrived spontaneously at 38 weeks. So yeah, the most I'd agree to would be either another S&S or having my waters broken. Providing all was favourable though.

Good luck with your decision.
