Mine have completely changed as well, don't feel bad. I think pregnancy and feeding in general completely changes the shape of your body. Mine were 12C pre-kids, then up to 14E while feeding and pg, and am now still a 14C even though with nothing on I look like a 12B at the most. All the skin that is there counts too I guess, best bet is to go and get fitted properly hun - in one bra I am a 12D instead of 14C so see how you go. xoxo
