Best place for petite maternity jeans???

Ok so kind of a random question but I wanted all of your advice. I am in the hunt for a cute pair of skinny maternity jeans which seems to be way harder to find than I thought it would be!! I am only 5'1 so I need either petite or just short length jeans in a size 0 or 2. I've tried old navy and they don't do a 0 and the 2s are too big, plus they are too long. I've looking in Macy's and on motherhood.com but they are really pricey and the ones I ordered from motherhood didn't fit nice at all. Does any one know of any where (in America- CA to be precise!) that sell good inexpensive clothes?? Thanks!  X
