Where are my contractions? - Dr. Visit 12/21

Ok, so I'm sure I'll be sorry I asked that question in a very short while, but I went to my almost-37-week visit today and I am already almost 4cm dilated and 80% effaced but because I am not having contractions I do not get to go to the hospital yet! That's a little scary to me because I just don't want to get in a situation where I can't make it to the hospital in time for my nice epidural. I've read things that say I could stay at this point for 2 or 3 more weeks, or she could come tonight, but I am 98% sure Edie will come within the next few days. Yay! Dr. says to lay low right now and pretty much decrease all extra activity because he doesn't want her to come for at least a few days since she would be fairly early and probably need time in the NICU. Very excited but also nervous for all that labor has to offer of course ;) Please keep us in your prayers and I'll keep everyone posted on my progress.
