Nursing/pregnancy bra help??

Anne
Where did you get yours (only if its comfy please! Local Wal-Mart and Meijer are out for me. After buying and returning 4 different ones I am done with them. Their selections are too small anyways) And how much did you pay? Also, size advice? (I've got 2 bras, that ive owned for 3 years. They are stretched out and well loved. Sized 40 D. Well this last nursing bra I got was a 40 DD. Way to tight in cups and around the back and sides. So what size do I go up to? Whats above DD? Nothing at Wal-Mart or Meijer that for sure!!) Thanks in advance lady. I'm struggling, lol
