All About Menstruation

Girls at your age talk a lot about periods. But what exactly is a period and what makes it happen?
Your first period is called menarche, your period is the 2 to 7 days that a girl or woman experiences menstrual flow –blood and tissue that leaves the body through the vagina-, to prevent this blood from staining your clothes you wear a pad which sticks to your underwear.

What goes On Inside?


The blood and tissue that leaves your body is no longer needed in your body. It comes from the uterus, the organ inside a woman’s body where a baby grows. What happens each month, is that blood and tissue that builds up in the uterus in case the woman becomes pregnant sheds away.

Let’s talk about eggs. They’re nothing like the eggs you buy in a carton at the store! Girls and women have two ovaries. Each of these ovaries holds thousands of eggs, which are tiny (each one is not bigger than the tip of a pin). During the menstrual cycle, an egg is released from one of the ovaries and begins a trip down one of the fallopian tubes to the uterus.

If a sperm cell does not fertilize the egg so it becomes a baby, the unfertilized egg and the lining from the uterus leave the body in the form of a period and the cycle begins again, and about 2 weeks after the last period, another egg will be released.

What’s a Cycle?

When people talk about the periods ,menstrual cycle or monthly cycle, they usually mean the 2-7 days when blood and tissue leaves the body through the vagina.
But the menstrual cycle is a process that takes about a month. A normal menstrual cycle for girls and teens ranges from 21 to 45 days. At most, only a week of the cycle involves blood and tissues exiting the body.
In the monthly cycle 2-7 days is the bleeding and the rest of time is the egg release and the uterus lining preparation.

When Periods Start

Most girls have their first period between ages of 10 and 15 years old, every girl will have her period when her body is ready.

What If My Periods Are Irregular? Usually periods stick to a regular schedule, the entire cycle takes the same number of days, but the first year of having your periods, your periods are usually irregular and hardly always try to track your periods on a calendar because after a while your periods starts to be regular and predictable.

What about Cramps?

If you have minor pain, you can take over-the-counter pain killer like ibuprofen. Other things you can do that may help with your cramps include:

  • Mild regular exercise
  • use heating pads on your lower abdomen

If this did not work out for you and you are still in pain or if your period prevents you from going to school, you should check with your doctor.

What about mood changes?

Hormone changes can cause girls’ mood to be unstable, you might feel more sad or irritable before your period starts. Being physically active is a natural mood lifter, so regular exercise often helps.
