Anyone had an ECV?

This is my first baby and at 36w1d (due Aug 16), he's still breech. The cord position is fine, but it looks like his pelvis is stuck in my pelvis. I've been doing inversions, exercises, Webster technique chiropractics... nothing has worked yet in the past 2 weeks to flip him. I'm scheduled for an ECV next Friday and was wondering what everyone's experiences were with that? Please only positive stories. I want to know what it's like. Thanks.
