The ovaries release the female hormones estrogen and progesterone . These hormones cause the lining of the uterus (or womb) to build up. The built-up lining is ready for a fertilized egg to attach to and start developing. If there is no fertilized egg, the lining breaks down and bleeds.
Girls' bodies usually become curvier. They gain weight on their hips, and their breasts develop, starting with just a little swelling under the nipple. Sometimes one breast might develop more quickly than the other, but most of the time they soon even out.
Most girls start their periods when they're about 12, but they can start as early as 8, so it's important to talk to girls from an early age to make sure they're prepared. Respond to questions or opportunities as they arise and do not be embarrassed. Periods are natural.
In girls, puberty usually begins between the ages of 9 and 14. Once it begins, it lasts about 2 to 5 years. But every child is different. And there is a wide range of what is “normal.” Your girl may begin puberty a little earlier or later and finish sooner or later than her friends.
"Periods last around 2 to 7 days, and women lose about 3 to 5 tablespoons of blood in a period," says Belfield. Some women bleed more heavily than this, but help is available if heavy periods are a problem. Find out about treatments for heavy periods.
