Im 20 years old I recently learned about the tanner scale for breast development. I firmly believe my breasts are in stage 4 although they should be stage 5. my areola is raised off of my breast and my nipple is raised above the areola. my bra size is 34A. left breast barely fills cup, right breast fills cup. onset of period age 11. started taking ortho cyclene birth control at 15 y/o due to severe menstrual cramps. no increase in breast size since 15 Why am I not in stage 5 like I should be?
