Every girl's body has its own schedule. There isn't one right age for a girl to get her period. But there are some clues that it will start soon:. A period happens because of changes in hormones in the body. Hormones are chemical messengers. 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.

That is why most girls and women get their periods around once a month. Ovulation pronounced: ov-yoo-LAY-shun is the release of an egg from the ovaries. The same hormones that cause the uterus lining to build up also cause an egg to leave one of the ovaries.
The egg travels through a thin tube called a fallopian tube to the uterus. If the egg is fertilized by a sperm cell, it attaches to the wall of the uterus, where over time it develops into a baby. If the egg is not fertilized, the uterus lining breaks down and bleeds, causing a period. For the first few years after a girl starts her period, it may not come regularly. This is normal at first.
