Mine didn’t work as it was intended and it wasn’t much fun but I don’t think my experience is common.
I was meant to have the balloon catheter but they couldn’t get it in. It was excruciating and they didn’t allow any gas and air. Instead they inserted the pessary which was uncomfortable but ok.
Unfortunately within minutes I had a reaction to the pessary, with instant, continuous awful contractions, projectile vomiting and diarrhea! It was called hyper stimulation of the uterus I think. The contractions weren’t “real” though as such. Anyway they removed the pessary pretty quickly and gave me codeine and it took many hours of walking the corridors to feel better. Walking helped the fake contractions stop, lying or sitting didn’t.
It was packed on the ward and I was basically waiting to see a consultant for Plan B (probably a section) when my waters went by themselves and I was 2cm. I was in pain so they suggested a bath. Contractions went mad in the bath, hardly any gap and when I got out an hour or so later I insisted on re-examination as it was so bad and unexpectedly for them I was 6cm so went straight to delivery and could have gas.
No time for an epidual which I was furious about and DD was born 6hrs later with gas and air, and 1 small shot of Pethidine to relax me as I got in to a right flap because my contractions were constant and in my back from the start and I lost all track of breathing etc. I had been really against opiates but the small amount I had really helped me calm down and when it wore off I was back in more control.
DD born with no tearing and I was bouncing around with no pain within minutes of her birth so it all ended very well.
I think the traumatic “failed” induction kicked it off naturally though IYSWIM.
