I thought I went up a cup size too, but the lady at the maternity store said that your ribcage expands, even early in pregnancy, and that it was more likely that my band size was too small rather than my cup size. So she fitted my bra with an extender ($2), and it was perfect! So much better than having to buy new bras! Yet, anyway.
