With DS, I was due the end of November. I think my old OB (don't go there anymore) stripped my membranes at an appt a couple weeks before DS' due date. The next day, my water broke, and DS was born by c-section (whole other story) the next day. I don't imagine my body would normally go almost two weeks early, so I guess I'm "planning" on going at least to my due date, and probably longer, as my body will kind of act like a 1st-time mama because of the CS.
I think generally, most 1st-time mamas go until their due date at least, but every baby is different and every pregnancy is different. It's crazy as your due date approaches, because each day you wake up thinking, "Will I have a baby today?" What fun!! :-)
I can understand the desire to nest and prepare for LO. Our baby shower is next weekend, so I hope we're able to kind of stock up on some of the things we'll need. We already have most of the big stuff from DS, so that's nice. Plus, my mom and a friend from out-of-town will be here for the shower, so I'm hoping they will be able to help us organize all of the hand-me-down clothes we've received for the new LO and get them put in our closet, etc.
