Membrane Sweep experience

Shelby • TTC #2!
I'm 39 weeks and I am scheduled to get my first membrane sweep today! I'm very anxious! I've heard so many mixed outcomes that I am trying VERY hard not to get my hopes up.. But let's be honest.,. I'm hoping it starts labor!  
Who else has had a membrane sweep and what was your experience?! Pain?? Outcome!? Advice? 
We are getting VERY excited to meet our little man!
