Most of the time, 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.
A girl's period, also known as menstruation, begins about 2 to 2½ years after her first signs of puberty. Breast development is usually the first sign of puberty, but sometimes pubic hair comes first. Girls usually get their first periods between the ages of 8 and 15.
Growing pubic hair: Just after your breasts start to form, you'll probably start growing pubic hair. It will be soft and thin at first, but it'll get coarser over time. Your period usually arrives around one to two years after.
The first period will typically begin a couple of years after the first signs of puberty appear. However, there is no precise way of knowing when it will begin. Several days before the first period, some females may notice spotting in their underwear or abdominal cramps. Some may also notice more acne appearing.
In the final stages of puberty, pubic hair may grow around the top of the thighs. Females will usually begin their period roughly 2 years after their breasts have started to grow.

Incomplete puberty
Children with early pubic hair development (typically between 6 years and 8 years of age) often have adult-like body odor and acne. Changes progress slowly. These early physical changes are not caused by a disorder, and only a few children go on to develop actual precocious puberty.
It is normal for production of these hormones to increase (something we call adrenarche) and for pubic hair to appear after age 8 in girls or 9 in boys. The reason why this increase occurs earlier in some children is not known.
Between the ages of 8 and 13, girls typically experience: Their breasts begin to bud, and their areolas (pigmented area around the nipple) enlarge. Scant pubic hair appears. Height increases by about 2¾ inches per year.
“There is no right or certain age to start shaving,” said Rashell Orey, a licensed master social worker at Banner Health. “Some may be eager to start very early, while for others, this could be a scary thought. It's a conversation that you'll need to discuss with them.”
The length of the anagen phase is based on genetics, but it can also be affected by hormones and stress levels. The anagen phase lasts between three and five years for head hair and a couple of weeks for pubic hair. The longer the anagen phase, the longer the hair grows.
Day 1 of your cycle is the first day of your period, meaning the first day of full flow (spotting doesn't count). During this time, the uterus sheds its lining from the previous cycle. Between days 1 – 5 of your cycle, new follicles (sacs of fluid containing eggs) begin to develop within your ovaries.
In most cases, there is no obvious or abnormal reason for why the body has started producing these hormones early, although body weight, heredity, ethnicity and activity can be important factors, according to Dr. Kreckman.
Most girls begin their periods between ages 9 and 18. The average is around 12 years old. If no periods have occurred when a girl is older than 15, further testing may be needed. The need is more urgent if she has gone through other normal changes that occur during puberty.
