So. I am 15 weeks pregnant with twins, and I have already outgrown all my bras. The problem is - how much bigger are my boobs gonna get???? I am reluctant to buy new bras when I will need a whole new set in a month. Do I buy nursing bras now? Or is there such a thing as maternity bras, which get bigger, like the pants do? I am so confused. Help a bewildered first time mother, Groupthink. Where is the best place to buy affordable but sturdy nursing/maternity bras, and when is the best time to buy them rather than suffer through some tight ones for a few more weeks?
