Maternity Clothes

Anna
I'm currently 31 weeks and haven't had to buy too many maternity clothes. I'm a teacher and have the summer off so I've basically been wearing lounge clothes all summer. I'm starting back work in about 2 weeks and was wondering where everyone gets maternity clothes. I've shopped at the local stores around me - Target, Ross, Motherhood, etc. Either those stores don't have much to choose from or it's wayyyy too expensive. (I only have 2 months left and don't want to spend a whole lot!) I've looked online as well but just wanted to see where everyone else thinks the best spot is to get maternity clothes. Thanks in advance!
