I posted this in the first trimester board, too, but I'm kind of in no man's land right now (14w, 4d). When did you / are you going to start shopping for maternity clothes? I'm fitting in regular clothes still, but stuff feels tight, especially as the day goes on.
Also, where are some good places to shop? Did you do it online or in store? I need work clothes and casual clothes.
Re: Shopping
Check your wardrobe for transitional items. I wore lots of "regular" dresses during my last pregnancy and it was fine. I did invest in some tops and jeans though. Check Zulilly.com for their maternity deals, and motherhood.com on their sales. I think a lot of their clothes are really overpriced, and I would never buy maternity clothes at full price. My favorite pants are Jessica Simpson brand over belly maternity skinny leg dark wash jeans. I could live in those things. I am not particularly an advocate of JS, and I would normally never wear skinny jeans, but they are really great. I got them on sale on line. Also, don't wait too long because you don't want to have to rush to the store when you're really pregnant to try on clothes.
good luck!
