My breast hurt they are getting bigger and my nipple is always point i've had a pregnancy test and it came out negative what could this mean ?

Hormonal fluctuation: Always perform bse( breast self examination ) and check for lumps or bumps. Breast size and tenerness can be influenced by many factors including female horonal variations; however, you must be examined by a physician. Since you are so young i would not worry- use gentle ( gym halter ) support bras and see if this is a monthly occurence. In some women breast growth continues into their 20s.
