I have been induced 4 times!!
first birth was spontanious
second was induced. One lot of gel at 9.30pm, gave birth at 4.19am......really easy, and no more painful than my first, fully 'normal' birth.
third, induced again, but needed 3 lots of gel as I was unable to walk and get things going.....I had fallen and split my pelvis first lot of gel 6am, then 12 noon, then 6pm, then I started to contract and baby was born at 12.31am.
fourth, again induced, this time due to having broken ribs in a car accident at 28weeks and by 36wks they were not healing.....bump got in the way. Induction was one lot of gel at about 9pm-ish, had baby at 9.51am following morning.
fifth, induced at 38wks, (very bad pregnancy and I was ill), gel in at 9pm-ish, baby born at 5.49am.
I have to say, none of my induced labours were any more painful than my un-induced labour and birth, and in fact, the pushing stage was quicker and easier. Mind you, pushing was probably easier because I had done it before and body 'knew' what it was doing.
good luck, and please don;t panic. You have already been through labour and birth once, so your body has had experience, and most of the time, second labours are easier because of this.
