It is true as the other poster stated that we all have different sized breasts, so it is nothing to worry about. I remember shyly talking to a friend about it in my freshman year of high school, and found out many others who had that same worry. They will even out in time, so no worries.
Hi, please don't worry about that. They grow at different rates, and every woman has two different sized breasts. Strange, but true! Same with our feet. One is slightly bigger than the other. Just one of those things we have to live with. They will even out some as you age. No worries!!
