Looking for Induction experience after PPROM (premature water breaking)

Hello, my waters have already broken and I will be induced next week in Rotunda at 37 weeks mark.
I am looking for induction experiences and timelines where waters have already broken.
How long does it take for the gel to soften the cervix?
Once the cervix is effaced, does the active labour start immediately?
Does the overall labour progress differently than normal induction?
Thanks in advance!!
