Just wanted to say been induced twice. Please note I generally am a bit rubbish with pain.
First time I had pessary, then another pessary, then waters broken, then syntocin drip. This all took a long time (around 2 days)!!
Due to it being an induction my midwives did completely restrict my moving around and I spent majority of time lying on my back, monitored, both times. Also when induced the first time, when drip went up I could move even less - essentially 13 hours in one position (this is difficult to cope with!) plus the contractions were then very painful, during this time I got the epidural (allowed to sit up for this!) and following that was catheterised several times.
Over those 2 days I was so nervous/excited I didnt sleep at all, so by the time I got to established labour I was knackered, then had an episitomy before ventouse delivery.
However all the monitoring did make me feel quite sure baby was doing fine throughout which I didnt expect to find as reasurring as I did. Also after epidural whole thing was virtually painless and I read paper/did puzzles whilst labour progressed.
Second time I got night sleep after first pessary and then easier faster induction and delivery.
I really dont think they would send your DP away if you needed him or if anything was happening. I sent mine away after first pessary both times (given in evening) so he'd be awake/alert when I needed him. But this was on understanding if any contractions were starting, the plan was to ring him to come back (only the mildest twinges for 12 hours to start with both times so I didnt bother). Ring midwife to put your mind at rest.
So my main advice is to sleep after first pessary and when possible if at all possible! Easier said than done!
My second advice is if they put up syntocin drip, consider epidural if this is an option for you.
Its definitely worth a go with TENS machine.
Overall I would like to go into labour myself next time but wouldnt be worried about induction again. And its true what they say about it all being worth it. Good luck for Friday.
