hi I had a failed induction not last wednesday but the wednesday before. (this is my 2nd)
basically the put the 24 hr pessary in, it looks like a long paper sperm and goes in like a tampon and they take it out after 24hrs, you have to go on the heartbeat monitors every 4hrs for about 20mins but you can stay active and walk around.
after this (if not in labour,)they will examine you to see how you are and probably will put the 2nd pessary in that stays in for 6hrs but dissolves on kts own and is like a tablet I think, you have to stay on your bed for an hour so that it doesnt fall out but then you can move around again, also you have the same monitoring with the heartbeat for baby but for the first 2hrs of this they will want to do your bp every half hr.
During your stsy they will keep intermittently doing yours obs though and take your temperature.
After this (if you haven't gone into labour, ) they will check you again and if you are about 3/4cms they will break your waters and give you so long, I think 2hrs; to start contacting, otherwise you will be hooked into the hormone drip- however they might just give you the 6hr pessary again, after a few hrs break.
I had all that but then had the 6hr pessary in again once more but it didnt really work, so they sent me home for rest days and are waiting fof my cervix to become more favorable before trying again to reduce the risk of c-section, apparently its very rare to still be pregnant! I've also been having two sweeps a week from just under 37weeks and they tried to induce me at 37weeks which is early for induction, I only managed to get to 1cm! But im an awkward and unusual case!
You can have pain relief if you need it, just ask and they will be more than happy to give you it and you can walk around as much as you like. When the first pessary is in (the 24hr one) you can bath with it in which is good for the pain. I found the pain to be in my bumcheeks and on my pelvic bone; felt very much like period pain for me; there were times it progressed but then it suddenly stopped!
hope that helps and good luck!
