Former Richmond Ballet dancer Shira Lanyi went through high school without getting her period. "My two older sisters had gotten theirs at 11, so my mom was so worried," says Lanyi, who didn't start her menstrual cycle until she was 26. At the time, Lanyi found her delayed puberty to be convenient. "To be honest, I was thankful because I was flat-chested, and that was great for dance."
But in fact, it's not okay for puberty and the things it brings (like your period) to be put on hold. The process is dictated by hormones that affect both your body and mind. While these hormones may be vilified for increasing the curves of your body and altering your moods, they make it possible for you to build up adequate bone mass and eventually bear children.
