Hey, what do you have against being flat? Someone in your family likely has genetically passed down her small chest—maybe your mom, dad’s mom or great aunt. So even though you’re going through puberty (getting your period is a sure sign that things are moving along), your boobs probably just aren’t built to burst out of your tank tops.
There’s till hope, of course. Your breasts should continue developing until you’re at least 18, says Dr. Adelaide Nardone, gynecologist and medical advisor to the Vagisil Women’s Health Center. You might also see an increase in chest size if you gain weight. For now, be patient. No pill or exercise will do the trick. Besides, you’re beautiful as is—think Kate Hudson! If you still feel self-conscious about your grapes not looking like melons, try a padded bra.
