I've had two inductions. They were both very positive experiences imo. I had zero birth plan though.
What types of induction methods you had that were successful?
If you mean successful to be putting you into labour, then the only thing that was successful in both my inductions was the drip.
Induction is usually a 3 part process. First part is cervical ripening, which are your pessaries, gels, balloons, rods etc. These are used to get your cervix ready (i.e. >=2cm) for step 2, which is manually breaking your waters (ARM). Both of these can be skipped if they've already happened. As others have experienced, they can trigger labour on their own. But if they don't (they wait a couple of hours to see if contractions start after the ARM), then if you wish to continue the induction, it's onto step 3, and the drip.
I had gel pessaries to start with both. First time because it was standard in my trust, second because baby was too high for a balloon. Managed ARMs (one midwife pushing baby into my pelvis while another popped my waters - I advise gas+air), then drip when contractions didn't start either time.
Did you still manage to incorporate hypnobirthing aspects e.g the exercises as well as the environment parts (mostly worried about the early labour part of this on the induction ward)?
Didn't do hypnobirthing. But then never had a contraction until I was in delivery suite, so early labour on the induction ward wasn't a thing. I just walked around outside, and chilled on my bed reading books.
How did you get on pain relief wise - any chance I could go with just gas and air?
Only you know what your pain tolerances are. There's a chance you could yes, but you won't know until you get there. I will say to be open to more stronger pain relief options though, especially with the drip.
I would say I have a high pain tolerance. I had gas+air up to the point it was no longer enough. My contractions started off mild, and got stronger and more frequent as the drip was ramped up. With my first, I had 5 hours on the drip (5cm dilated), then had diamorphine. 6 hours of being sound asleep between contractions later I was 10cm. Second it was a similar story, except it was 10 hours to get to the same dilatation, so I opted for an epidural as who knew how long full dilation would be.
Was anyone induced and still managed to use a pool / birth centre?
I would genuinely manage your expectations on this one. If you do have OC, then you will be going to delivery suite. Birthing centres do not handle anything more than low risk patients. If you need the drip, then (in my trust anyway) the pool is no longer an option. It's not an option ifq you're on delivery suite usually anyway tbf. Only one room (out of 10+) has a pool.
