PUBERTY IN GIRLS
Puberty is a time of many changes, A girl's body starts changing after about age 8. Many Girls worry that they are not developing fast enough, or are concerned if they develop befor their friends do. Remember, each person has her own timetable. Some girls start puberty early, and some start later.
Most of changes of puberty are caused by chemicals called " hormons" that the body starts to produce. The main female hormons are estrogen and progesterone.
Breast start to grow when a girls is between 9 and 13. Many girls are concerned about the size and shape of their breast. Breasts comes in many diffrent sizes. So girls shouldn't worry if theirs are diffrent from their friends.
One breast may grow more quickly than the other, however, they will be about the same size when they finish growing. Public and underarm hair will start to grow next.
Menstrual periods ussualy star between the ages of 11 and 15, however, periods can begin as early as 9 and as late as 17.
This is what causes a period : about once month, a woman's body gets itself ready for pregnancy. The lining of the womb, or uterus, starta to thicken. About 2 weeks later, one of the ovaries releases an egg, or ovum. If sperm from men's body does not join with the egg, that is, it is not fertilized, then the thick lining of the uterus is not needed. In about another two weeks, her body gets rid of this lining through the vagina. This is called having a period, or menstruation.
Many women are uncomfortable or have cramps during their periods. Excercise, a heating pad or hot water bottle, and a pain reliever can help. If these ideas don't work, ask a doctor or school nurse for help.
Period ussually last between 3 and 7 days. They may be longer or shorter, and bleeding may be heavier in some months than in other - especially when you first start having your period. Many things can affect your period, such as strees or sickness or fast weight loss. After a while, most women find that their periods become regular. Once periods are more regular, they happen about every 21 to 35 days, or 3 to 5 weeks.
If a women has intercourse then misses her period, she might be pregnant. If sperm joins with an egg a pregnant begins. The fertilized egg attaches itself to the thick linning of her uterus and starts to grow. Her body does not get ride of the linning and she does not have a menstrual period.
The female hormones also cause a woman's vagina to produce a discharge or mucus. This doesn't hurt or itch or smell bad, However, if u have a discharge that does hurt or itch or smell strong, see your doctor, you might have an infection.
Pimple or acne are common problem. Some suggestions re to wash with plain soap, not eat foods with lots of fat, not use skin moisturizers, and use lotions with benzoyl peroxide which can be bought without prescription at drug store. A doctor may also be able to prescribe medication.
