If I remember right with my first(6years ago) the pitocin made the contractions so unbearable I screamed for the epidural but they were too busy because 4 other moms were actually pushing right at that moment AND they had an emergency c section. So I had to scream for an hour. Terrible. But I'm not trying to scare you, it was all worth it in the end anyways. And I was in labor 17 hours prior to that it wasn't all that painful. Just an hour of misery lol. Best of luck to you, soon you'll be holding your little one :)
I'll be 41 weeks tomorrow.
