Scheduled to try and flip my baby on April 30th

So my doc scheduled me to go to labor and delivery on April 30th to try to turn my breeched baby .. I'm a little nervous bc his umbilical cord can get wrapped around his neck during and then I could be rushed for a emergency c section .. Hoping for positive results :) in the mean time I've been having horrible lower back pain and contractions more and more .. Hope things go smooth and planned .. Anyone have this done before ? Or expiriancing this?
