Pants

Now that I've hit the four month mark, my pouch is starting to poof a bit and my usual jeans are becoming a bit uncomfortable. In fact, I only wear jeans when I absolutely have to leave the house in something other than exercise pants. It has recently become kind of a big deal, and the idea of having to wear either tight/unbuttoned jeans or frog pajama pants to a birth is making me somewhat anxious. Where am I going to find a suitable pair of affordable, plus-size, short length maternity pants to wear to work??
