Sorry you are feeling the frustration! I think there is an issue of women being given the impression that quick induction is guaranteed.
When I had DS I went for induction at 38wks due to gestational diabetes. I was firmly told it was dangerous for him to stay in longer as the placenta could fail, so if the induction didn't work after 3 days I would be recommended a cs.
The reality was I went in at 7am Tuesday, had the 24 hr pessary, then 2/3 further treatments. I was having mildly painful contractions from Tuesday eve but I was never more than 1cm. I had a birth ball and spent hours pacing the corridors.
The Friday consultant seemed unconcerned and said I could go home and try again next week. By then I was worrying about the placenta and a bit crazy from being stuck in hospital and all the contractions. I was finding internals increasingly painful and she was really rough. A lovely mw overheard and said she would speak to someone about how I was being treated and suddenly it was all change and I was being prepped for theatre.
The cs was a wonderful calm experience and I had my DS placed straight onto my chest, established bf and was home after 2 nights.
Now at 36+4 with DC2 I have declined induction and am booked for a cs at 39 wks.
I'm hoping while I've been writing and remembering this that you've had lots of smooth progress and are soon holding your baby. Good luck!
