Large boobs-bra recommendations please!

I have a very large chest already...LIKE 36GG. My boobs have been soooo sore! My doc suggested getting fitted for a new bra. It's even painful turning over in bed without a bra on. Any other large chested women have suggestions on a comfortable bra that I can wear during pregnancy, even potentially at night? And any nursing bra recommendations are appreciated too. Shopping at Target or Victoria Secret for a bra is sadly not an option for my gigant watermelons! Thanks!
