Hey C, hope you are having a nice day together with your son today 
Don't worry, you will be OK
I think it's normal to worry about change, I did going from 3 to 4 kids.
I have never been induced but make sure you ask lots of questions and if you want an epi ask when they can give it to you, make it clear from the beginning that you want one. Hopefully the pessary will be enough but they might want to use something stronger if it doesn't and that may bring on very strong contractions straightaway, hence the need for an epi 
Good luck!
Soon you'll be holding your baby girl!
