Was induced both times (DS 2002, DD 2006), due to 'essential hypertension' i.e. had mild blood-pressure probs when pg and was on medication, although had otherwise normal pregnancies with no pre-eclampsia or other symptoms. Do not have bp probs when not pg....
Anyway, both experiences were fine.
DS: one lot of gel pessary (cervix was 'favourable') in evening and in morning. Started labouring at noon and he was born at 8.30. Had no further intervention, only a bit of gas and air, although he had to have forceps to help him out at the end (cord round neck).
DD: 'propess' t-bag thingy (due to cervix being 'unfavourable') in morning and was told it would take 24hrs to work. On cue, waters broke 9am following day and DD born 1.30. Again, no other intervention (drips, epidurals or other drugs), and had a tear (she was face to pubis and almost 9lbs! - would have probably had this whether labour was induced or started naturally!)
So the 2nd one was shorter than the first (4.5 hrs compared to 8.5 hrs) but this would be true if labour started 'naturally' wouldn't it, as 2nd labours are usually shorter anyway?
Friends I have spoken to claim that their inductions were very intense, but these involved drips as well as the initial gel pessaries. Both my labours felt 'natural' once they had started - I did not feel that the pain was out of control at any point.
With DD, having had the hospital experience with DS and feeling more confident about knowing the drill a bit more, I was very insistent that I wanted no further intervention once the induction had happened, unless I said so, and the mws were very supportive of this - so my advice would be not to get intimidated by the consultant/doctors/hospital atmosphere and remain focussed on what you want.
Sorry for long post. HTH and good luck
