I had a similar experience to lots of others here:
Went in Friday morning expecting to have baby by 5pm, when it was actually early hours of Monday morning! Lots and lots of waiting around and walking round the hospital at all hours
Pessaries had very little effect at all
Had to have my waters broken, made no difference
Started the drip around 4pm, baby needed help (forceps) to be born at 1am.
I do regret putting off having an epidural, once I decided I wanted it, I wanted it there and then but no anaesthetist was available for almost an hour!
Contractions are almost continual with very little time to recover in between and there is no gradual build up, they just come on full strength once the drip kicks in.
Quite often, inductions need assisted delivery so it's worth being prepared for this. Once I had the epidural, I couldn't tell when to push, so needed some help.
Looking back, it was really intense but not that bad, I expected it to be much worse!
Hope it all goes ok :)
