My wife's contractions have been less than 5 minutes apart for over an hour and a half. Intensity has picked up a bit too. Consulting the on-call doctor (Her normal doc, an ND grad, has said this is the only night between December 1 and March 1 that he isn't available.) now. This isn't the first go round so we're not all panicky yet. For the record, I've been calling this since the USC game, even though it's 8 days early.
