My boobs don't usually change too much when I'm pregnant but this time around they definitely are. I am usually a C cup but I'm busting out of those big time. I need to pick up some support bras.
I was sitting smaller for a while since I'm still nursing. But I have noticed in the past week or two getting fuller and filling my bras out quite a bit more. I'm starting at a F/G, so I really don't care for them to get bigger. I did go up to an I/J when my milk first came in with DD. That was just ridiculous.
