Most girls get their first period between the age of 9 and 16, and puberty normally begins around the age of 8 to 14. Most girls will not start menstruation until they weigh at least 100 pounds. Puberty hormones lead to girls developing breast, hips, pubic hair, and growing in height.
Your periods will start when your body is ready. This is usually between age 8 and 17, or 2 years after your first signs of puberty. Possible reasons for delayed periods include being underweight, doing lots of exercise (including dance, gymnastics and athletics), stress and a hormone imbalance.

Nutrition, energy balance and hormones interplay in growth and pubertal development regulation. Frequently overweight and obese children are taller for their age and sex and tend to mature earlier than lean children.
Poor nutrition alters the ratio of lean mass to body fat and delays the onset of menarche. In the US, the age at menarche decreased by 3 years since 1840 due to improvements in the population's nutritional status. Underweight females generally experience menarche at later ages than normal weight females.
Puberty in women normally occurs between 11 and 14 years of age. If a girl reaches a particular weight (around 100 lb (45 kg)), the onset of puberty is triggered. The heavier the child, the earlier puberty occurs, possibly affecting risk of later disease.
Hormone levels are affected by your weight and the amount of fat on your body. If you are underweight, with too little body fat, you may skip periods. Too much fat can also lead to missed periods or heavy periods. Rapid weight fluctuations can also interfere with your menstrual cycle.
"When estrogen peaks during the days right after a woman's period, and leading up to ovulation, the cells in the skin are stimulated to make more of these elements, resulting in a clear, glowing complexion. During this week, estrogen not only stimulates a glow but also keeps testosterone in check by shrinking pores.
Amenorrhea has many causes, including hormone problems, eating habits and exercise, or a birth defect. Your teen may need blood tests and a pelvic ultrasound. Treatment may be done with hormones or other medicines, changes in diet or exercise, and calcium supplements.

Girls usually get their first menstrual period when they're 12 or 13. It's a sign that your body is maturing, so that one day, if you want to, you should be able to have a baby. By age 15, 98% of teens have started their periods. If you're not one of them, make an appointment to talk to your doctor.
If your daughter hasn't had her first menstrual cycle by 15, or if more than three years have passed since she started developing breasts, she should see a physician.
Typically, a girl gets her period about 2 years after her breasts start to develop. Another sign is vaginal discharge fluid (sort of like mucus) that a girl might see or feel on her underwear. This discharge usually begins about 6 months to a year before a girl gets her first period.

Excessive or sudden weight loss can cause your periods to stop. Severely restricting the amount of calories you eat stops the production of hormones needed for ovulation.

A period is considered late if it has not started within seven days (one week) of when it is expected.
Growth Spurt Ages and Normal Growth
Generally, girls get more curvy and boys get more muscular. The timing of weight gain is something to note as well. The growth spurt ages differ for boys and girls. During the start of puberty, around age 10 to 12, girls begin to see a lot of body changes.
They also gain more fat than boys in preparation for their menstrual cycle. They go from gaining about 5 pounds a year before puberty, to 12-23 pounds during puberty as shown below. Girls' growth happens in stages as they tend to fill out before they grow up.
