Hi! I love the Medela bras. They are wonderful and only about 30-40 dollars. I found out that they not only sell them at your local hospital's breastfeeding support center, but also at Gap Body and Motherhood/Mimi stores. I normally wear a 32dd but while nursing I'm in a 36E (DD)...they have DDD too and 34's. So they should have what you are looking for! Here's the link to the bra I use:

Also: They sell both underwire and softcup...I use the softcup too because I hear underwire isn't good while nursing. I also love the shoulder straps (very comfy) and the back closure (4 hooks...not wimpy at all!). Good luck and congrats on the lil girl! I have a 3 yr old boy and a 6 week old girl!
