Pay Attention to Her Period

If your daughter hasn't gotten her first period by age 14, or if she misses her period anytime for three to six months in a row, see a doctor. Delayed puberty or missed periods may be the result of excessive dieting and overexercising, and can trigger the fall of estrogen levels, compromising peak bone mass, explains Saralyn Mark, M.D., associate professor of medicine and ob-gyn at Yale University and Georgetown University School of Medicine.
