What size maternity bra should I be buying?

[Yas]

I would be buying some cheap wire free bras for now, my breasts went up multiple cups throughout my pregnancies and went up AGAIN once my milk came in.

I agree- iv'e gone up 3 sizes this pg. I'm normally a 10B and when my milk came in last time i was a 10DD.

I would hold out as long as you can on buying bras and then get professionally fitted.
I bought my Pregnancy BF underwire bras online..Frayer maternity and very comfortable. I went from a 10c to 10DD-E.
When you milk first comes in you may find you may not be able to wear a bra at all and wear something like a BF singlet that has like a shelf bra. When it settles down you should be able to go to wearing a BF bra. It was around 8-10days after giving birth that I started to wear a BF bra.

I would also recommend buying a few cheapies for now, and buy new ones as you need them. I went from a 12B to currently wearing 14C, when i fell pregnant they grew, my milk came in, they got even bigger, once BF was established they went back down.

I was a 10B before DS... within the first tri i had the same problem very sore boobs and i also went up a little bit so i bought wirefree but normal bras in a 10c. when my milk first came in i went up to a 10D and i bought one in that size but at home i lived in bfing crop bras and the triangle ones (from kmart). Found them easier at home. Then once i settled down after a few weeks i went back to a 10c however you can only get expensive bras in that size for bfing from specialised places i had to settle for a 12c. I couldn't justify spending that amount of money for only a few short months. so i lived alot in the crops.
From when my son was about 12months old i have gone back to being a 10A!! and i'm still feeding and i'm that size... which totally sucks to get bras now! i'm in kids crop tops! sad ....

i have splurged and bought a bra from Intimo in a 10B so far for this pregnancy cuz i think in overall time i spent the most in that size (from about 5month -12months old). hope that is some help.
