Hello Magpie.
Induced just over a year ago for raised BP and like you, had to wait a week from admission to hospital because it was Christmas week and the maternity ward was like a zoo.
I had a total of 7 sweeps, mostly because I was determined I wanted to go into labour on my own. I found the first few sweeps gave me a massive endorphin high, which I'm sure would have been really helpful had I gone into spontaneous labour.
As it was, I didn't and after 6 days waiting on the maternity ward, I had a bit of a battle with the midwife in charge to let me go home and sleep in my own bed ( by then, I was sleep deprived, constipated and in no fit state to give birth).
Came back the next morning and taken straight down to delivery suite for ARM, so missed out on pessary, balloon etc. Saw other girls on ward given pessary and it seemed to either not work, or put them into good going labour within a few hours. Think they were keeping people in the ward as long as possible because it was exceptionally busy.
ARM was painless and done by a male junior doctor who I will never forget for his gentleness ( better than any of the female staff). Labour started really quickly after that and progressed from easy to manageable in an hour, then manageable to 'maybe need to speak to anaesthetist' in the next hour. Ramped up really fast after that and they gave me diamorphine, I think just one shot. I was able to get up to go to the loo, but once things really got going, all I could do was lie there mooing and sucking on gas and air and let it happen.
It wasn't frightening, but it was very very intense. Didn't need to push, in fact the midwife was trying to hold DD back and she was born needing a little puff of oxygen because of the diamorphine exactly six hours after the ARM.
Second degree tear stitched up painlessly on G+A and a diclofenac suppository popped in for good measure. Healed well, although about six months to really feel normal again.
Worst thing about induction was the massive cannula they have to try and get in your hand so you can be given meds and fluids if you need an emcs. Getting it in was painful and I don't think in my case it was located correctly. Ended up over the bone in my wrist, as it had to point skywards if you were lying down for theatre.
And constipation afterwards. For weeks. Keep your fluids up and make a point of asking for all the help they can give you before and after.
In all, mine was really positive. A good birth, even if it wasn't the one I planned. Now pregnant again with no.2 and would happily have another induction, especially because we live 40 mins from hospital and I could not have done the journey in labour!
Good luck and feel free to PM if I can give any more information.
