I wanted to second fairymom's recommendation of a babywearing coat! They are expensive, but I have seen used ones out there - try thebabywearer.com, where there is a buy/sell/trade forum. If you are planning more children and/or doing a lot of babywearing, this is totally the way to go.
I bought a first generation Kindercoat back in the winter of 2005/06 and it was a godsend. I bought a medium, which fit me (5'5" tall, about a size 10), DH (5'8" tall, 170, men's medium) AND our babysitter (5'10" tall, about a size 14/16) through that first winter of carrying DS (who had been born the previous May). The second winter only I was still babywearing, but the coat still fit. (Note that my backup option - a Ralph Lauren wool hunting/barn jacket, men's size Large, that I bought at a rummage sale for $5 - very warm and pretty good-looking, considering - did NOT button around the two of us at that point, though the Kindercoat did.)
The design has been tweaked and is probably close to perfected by now, but I think the basics are the same: an outer coat that is like water-resistant ski parka material, with an inner removable fleece liner that can also be worn separately as a zip-up fleece jacket. If you are babywearing, the coat is engineered so that you can wear the baby on the front by zipping in an extra panel (which has that same removable fleece liner), or on the back by opening a zipper between the shoulder blades and a gusset that runs down either side on the back. Obviously the part you care about when you are pg is the extra panel that zips down the front.
Right now I'm wearing an A-line trenchcoat with a removable lining, and I can still zip/button over my belly, though I don't think it will last me more than another month or so. Once I'm huge and the really cold weather hits, I'm switching to the Kindercoat.
