Induction with pill inserted in vagina?

I’m not sure of the name, but has anyone had this done?

My doctor said i could get this or possibly pitocin when i go in tonight for my induction. I know pitocin is through an IV, but she mentioned that there is another way that is inserted vaginally and I’m a little worried about that.

How painful is it to insert? Do they have to do it multiple times? Does it start contractions right away or just soften the cervix? Is it only for someone who’s cervix is still hard?
