Hi Smoochyschmoo
Short answer - yes - your womb will already have oxytocin receptors left after your last two deliveries so it should be relatively plain sailing for you.
If your cervix is soft and 2cm you may not need the pessary/gel, they may go straight to breaking your waters. If your body starts contracting after the breaking waters, you may not even need the drip!
The good thing about the drip is it starts low and can easily be turned down or stopped. The gels cannot be stopped once they're in, so if you are very sensitive to them it can lead to the situation FATEdestiny describes. Theoretically the pessary is more controllable because it can be taken out, but it takes a short while to wear off.
The purpose of the vaginal gels/pessaries are 1) to make it possible to break the waters, and 2) prepare the cervix and require less time on the drip. In my experience, doctors tend to be keener to perform a difficult ARM (water breaking), midwives tend to err on the side of giving you vaginal prostaglandins to ripen the cervix further. If you're really worried about what FATEdestiny describes, you can ask them to break the waters whenever possible, and to use a pessary rather than a gel. Then, if you start to get significant contractions, you can ask for an examination immediately.
Personally, it sounds like you might be able to go straight to the waters-breaking phase.
Finally, contrary to popular belief your consultant is right - there has been a couple of good studies now suggesting induction does not increase the chances of emergency CS (in fact, slightly decreases it) and similarly does not affect the rate at which people need forceps etc. There will always be individual cases like the one above that buck this overall trend of course.
Hope that helps!
