I have had my period for about a year, does that mean my breast are done growing?
Getting your period and developing breasts are both things that happen during puberty, but everyone experiences puberty at different rates and times. For most girls, puberty takes several years, and usually happens between the ages of nine and 17. Some girls, however, are not fully developed until they are 20. Girls’ breasts usually bud before their first period, but full development of the breast goes on for some time after. Breasts continue to change somewhat throughout a woman’s life. Weight gain and loss, pregnancy, and menopause all affect the size and shape of the breast.
