I gave up on nursing bras too. I have actually spent the last 18 months wearing the
Glamorise Magic Lift Plus Active Support Bra from Just My Size. I pull up one cup when I want to nurse.
I need a new bra too, and badly, but I'm putting it off til after the baby gets here & my milk comes in. I was told during my first pregnancy that you'll gain a cup size when your milk comes in, and while that was true for my first pregnancy, it wasn't for my second...but then I didn't go up hardly at all during pregnancy last time either, and I have this time. I want to buy an "unbra" from
Decent Exposures, but they're expensive enough that I really need to wait to make sure I get the right size!
You're not too far outside the norm as far as cup size goes, though. So if you want to get a bra now, I'd get one that fits multiple cup sizes. I have heard good things about
Bravado's Original Nursing Bra. Something like their L size, which fits 38 - 42 E - G cups, would probably carry you through the end of pregnancy and into nursing, since you probably won't get bigger than a G.
