Periods (Menstrual Cycle)
What is it?
The time when a girl's uterus releases blood out of her body
This blood comes out through her genitals
It happens about once a month
Why does it happen?
It's a natural process
It's part of growing up and becoming an adult
During puberty, girls' bodies prepare for future reproduction
The body releases a hormone called estrogen
What happens inside the body?
Girls have two ovaries with tiny sacs called follicles
Each follicle has one unfertilized egg
Ovulation: The most mature egg bursts out of a follicle
The egg travels through the fallopian tube to the uterus
The uterus has a lining called the endometrium, which thickens with blood and nutrients
Implantation: If fertilized, the egg attaches to the endometrium and grows into a baby
If not fertilized:
The body doesn't need the thick endometrium
The body breaks down the endometrium
Blood and tissue leave the body through the genitals (this is the period)
The whole process starts again
Important Facts to Remember
A period is natural
There is nothing impure, gross, or embarrassing about it
Girls may feel pain in their tummy
The pain can last for a few days (up to five days)
Be kind and understanding to friends who are having their period
You can help by offering sanitary pads or pain medicine (if allowed)
Most girls lose about 2 to 3 tablespoons of blood during their whole period
Some female animals also have menstruation
