Hi, I was induced with pessary first, 1cm, quite favourable. Spent the first day in hospital with not a lot happening, the second day I was given another pessary and started getting some light contractions. Did a lot of walking and bouncing on a ball, my contractions intensified but nothing came of it. I ended up having my waters broken and onto the drip but after 8 hours of consistent contractions I was checked and was still only 2cm dilated! By this point my baby's heartbeat was dropping significantly and I ended up with an emergency caesarean, under a general unfortunately.
This was just my experience, talking to midwives during the whole process some were saying many women go into full on labour just from the first pessary, others as soon as on the drip women had their babies within hours. My sister had exactly the same experience as me so I think maybe our babies just didnt want to come out haha. Hope it all goes well and is quick for you x
