My OB has suggested it when we have a third if my body is favourable at 38 weeks.

Both my girls were spontaneous, DD1 at 38+5 and DD2 at 38+4. I had SROM at home with both. DD1 was born just under 8 hrs after my waters broke. She was a tough posterior labour with over an hour of pushing followed by a vacuum delivery. DD2 was about 45 minutes from my first contraction Active labour was actually recorded as 37 minutes. Fast labours have been common on my mum's side

I don't want a home, car or roadside birth therefore I'd be happy to have some sort of intervention, I think, in the 38th week given that I've gone into labour that week with both our girls. I'm not keen on anything medical as such though so I'd start with a S&S and then maybe get my waters broken.

My OB had told us to call an ambulance if DD2 had decided to arrive during peak hour. Thankfully it was a Sunday and I had a about 2.5 hrs between when my waters broke and when labour started.
