It's a dress rehearsal - where everyone is running the show at 50%. I've been having practice contractions (aka Braxton Hicks) for a few weeks. Though over the last two days they have become more frequent and more intense. The good news is they are still not rhythmic and with a little hydration and change of position - I can put a stop to them pretty quickly. It's marvelous the way your body gives you a snapshot of what's to come.
