Just curious. my breast have been real tender and seemed to have grown. im 21 almost 22 is this normal n if so how long will they continue to grow?

Can be normal.: There are many reasons your breast may be sore- have you recently started or changed birth control? Could you be pregnant? Have you gained weight recently? Where are you i your cycle? There are many reasons breasts can be sore and swollen, not just a growth spurt. Make sure you are wearing a good fitting bra and that should help some with the soreness.
