Hi Louise,
When I was induced I thought I was going to have to have the gel/pessasry but the doctor said as I was 2cm dialated they could just break my waters, he said if a midwife can get in to your cervix to do a sweep then they can get in to break your waters......I would ask about this as it may speed things up just a little (you'd not have to hang around waiting for the gel to take effect)
I thought it would hurt having my waters broken but I didn't feel a thing - infact I found it quite funny that there was so much of the stuff!
If you can have that done and get hooked up to the drip things normally start to happen pretty quickly (or they did with me)
If your not keen on the Gas & Air or Diamorphine then I'd definately reconmend the epidural (it doesn't hurt!) and have it sooner rather than later as you have to keep really still and its quite hard to do when your contractions are close together, you can let it ware off towards the end so you can feel the pushes!
My Labour was 18hours and 13mins (I'm still nagging chris about it

) although had Noah been facing the right way I'm sure it would have been a whole lot quicker.......he just got too comfy and didn't want to come!
At one point in my Labour I did want a c-section and when they said about it I just asked If I could have one, I thought if they don't know if anything else is going to work then why don't they just do the way it will work? I'm now so glad I didn't have one as I wouldn't be 100% mobile for 6 weeks and would struggle to feed, change etc! I stayed in hospotal 1 night but I think that was more to do with having to be cut and my blood loss! It was ok being in hospital as there was always a midwife on hand when I was stuck with something or worried, if i was at home straight away I probably would have worried myself at every little move he made!
I know its so so hard but try to relax and just go with what the doctors reconmend, just think if you get induced this time next week you will have your little boy and you'll probably be thinking 'what was I so worried about?'
Its the most amazing feeling in the world seeing your little baby, I didn't have a very good labour but would do it all again tomorrow!
Good Luck xxx
