Some of us just don't get much boobage. I myself don't have much upstairs but mom has an A cup so I couldn't really have expected more. I'm just planning on BA after I'm retired from derby (so as to avoid a pop), personally. Progesterone might help but, really, if you've got small boobs, there's only so much it can do. Hate to be blunt but, I don't want you pinning all your hope on something like that.
