Hello,
I was induced, as above it started with a pessary, then if that doesnt work they break your waters if that is possible and if that doesnt work they give you a hormone drip to make you contract.
The NCt antenatal classes I went to told me a lot of women opt of an epidural at the point of the drip as it can bring contractions on more quickly than a natural labour. In theory a natural labour allows your body to build up resistance to the pain to a degree as it starts of slow and not too bad and increases with time however an induction can make things happen very quickly and you dont get the slow build up.
I dont think you have to stay in hospital any longer than with starting labour on your own,however i ended up in four days as i had some kind of infection.
I thought the pessary gave me a lot of pain - the midwife said i wasnt even in labour and i was very uncomfy , but a work colleague has had two inductions and needed no pain relief apart from warm bath so like any labour it varies woman to woman.
Try not to worry too much (easier said than done) I am sure it will be fine, you may even go into labour before they have to start you off.... hopefully tonight will be the night for you!!!
Good Luck with everything.
