Induction gel! Someone clue me in!

Rachel
So went to the doctor today and was not expecting to hear that we need to be induced tonight due to low amniotic fluid!? My husband said "well, you're at the end, what did you really expect at these last appointments?" Funny dude...anyways, have any other mommies had the gel before? Does it hurt when they put it up there? Do they start an iv right away?!
