No pitocin? That's awesome. Usually they pit you as soon as your water breaks.
make sure to get enough vitamin C this pregnancy to prevent the water from breaking too long before labor starts is my counsel. It strengthens the sac. Also, know that the risk of infection doesn't increase for 48 hours as long as nothing goes into the vagina after your water breaks, and that most women give birth in that timeframe :) And the risk of stillbirth and complications doesn't increase until 42 weeks (not 41). So induction prior to that is increasing risks unnecessarily unless there is a medical reason.
It sounds like you have average gestations. Like I said, don't count on a shorter pregnancy, because every single one is different, but I would guess that this one will be born right around his due date.
