I am 13 years old, im not quite regular so i couldnt tell you if i was about to start my period, but that doesnt really matter, every minute of every day my boobs are killing me. I cant put any pressure on them at all. Since i sleep on my stomach its starting to mess with how well i sleep. It only bothers me bad when im not really doing anything important. but in sports when im jumping and running its not that unbarable, but during school and at home, they kill me!!! please help me if you can and thanks so much.
