I'm 11 weeks and am finding that I grew slightly in cup size but not enough to go to the next cup. It seems like my rib cage is getting thicker. I went from a 36 B to a 38 B and now the 38 B is digging in around my ribs.  I haven't gained any weight. I've actually lost weight. Anyone else having this trouble?  I'm hoping that the area around my ribs will go back down to a 36 someday. I have so many bras I can't wear!
