asymmetrical boobs

lauren

im 17, im overweight and i have asymmetrical boobs. my left boob is b (when im on my period, it can almost 'spill' out of my bra. but my right boob is a. i know that boobs are not always the same size, but mine is kinda far in sizes. i hate looking at it sometimes, cause i want to have 'normal' boobs like other girls. will it become more balanced if i lose weight or something? what can i do about it?
