Most young people will have their first periods when they're between 11 and 14½, but anywhere from 9-16 years is considered normal. Periods are likely to start soon if your child has: had a major growth spurt. grown some underarm and pubic hair.
For most girls, their first menstrual period, or menarche (say: MEH-nar-kee), begins about 2 years after she first starts to get breasts. For most girls this is around age 12. But it can be as early as age 8 or as late as 15.
However, anytime between 10 and 15 is within the average range. It's not entirely unusual for a first period to happen as young as 8 or as old as 16.
Early periods often result from hormonal changes, especially during puberty and perimenopause. Many underlying medical conditions, including polycystic ovary syndrome (PCOS) and endometriosis, can also cause menstrual irregularities.
Girls usually stop growing taller about 2 years after starting their menstrual period. Your genes (the code of information you inherited from your parents) will decide many things during this time, including: your height, your weight, the size of your breasts and even how much hair you have on your body.

When do most girls get their period? Most girls get their first period when they're between 10 and 15 years old. The average age is 12, but every girl's body has its own schedule. Although there's no one right age for a girl to get her period, there are some clues that it will start soon.
Guys don't have periods because they don't have a uterus, but their bodies develop and change too – the changes are just different. For example: their voice changes and they develop hair on their face and other parts of their bodies. So, although guys don't get periods, their bodies do go through changes too.
Overview. Menopause is the time that marks the end of your menstrual cycles. It's diagnosed after you've gone 12 months without a menstrual period. Menopause can happen in your 40s or 50s, but the average age is 51 in the United States.
Several days before the first period, some females may notice spotting in their underwear or abdominal cramps. Some may also notice more acne appearing. Not everyone will experience this, however.
The first period often is very heavy and painful. Ovulation, or the process of making an egg, helps make a “normal” period. Unfortunately, many girls do not ovulate in the beginning, resulting in heavy bleeding. Some girls also may have a bleeding problem that shows up when they start having periods.
At the beginning or end of your period, blood can be a dark brown/red shade and can have a thick consistency—but it's also normal for the first signs of your period to be bright red and more liquid.
A breast bud is like a small raised bump behind the nipple. After breast budding happens, the nipple and the circle of skin around the nipple (called the areola) get bigger and a little darker. Then the area around the nipple and areola starts to grow into a breast.

That means axillary (underarm) hair, pubic hair, breast development, body odor, and mild acne is normal in eight-year-olds is normal. Girls typically begin their period two years after breast buds appear, the youngest age being ten.
