- Getting sick more often
- Feeling less motivated

- Having lower self-esteem

Everyone develops at their own rate. A doctor should be consulted for girls who have not gotten their periods by age 15 or within a few years of breast growth. It is important to note that some girls don't get their periods until they're 16. Often the best predictor of when a girl will get her first period is when her mother got her first period.

Puberty is the process of developing from a child to sexual maturity. In girls, puberty includes:
- growth spurts
- development of breasts and hips, growth of body hair
- the beginning of menstruation (having periods)

It's a myth that oily foods or chocolate cause pimples. Acne is caused by overactive oil glands in the skin. If certain foods seem to cause you to break out, try to avoid them. But you don't need to shun pizza or chocolate for clear skin.

Condoms can't protect you from all STDs, and birth control pills do not protect against any STDs. Abstinence (not having sex at all) is the only 100% sure way to not get an STD.

Many teens think that if they have oral sex -- but not sexual intercourse -- they can't catch an STD, but many STDs can be spread through oral sex.

By the age of 21, almost 20% (one in five people) in the U.S. will need to be treated for an STD. This accounts for half of the new cases of STDs in the U.S. every year. In fact, it has been estimated that up to 15%-20% of sexually active adolescents are infected with Chlamydia trachomatis (a common STD).

You may be confused about what you should and shouldn't eat to stay healthy. In fact, making healthy food choices isn't hard at all. To help prevent heart disease and some other diseases, you should eat mainly:
- fruits and vegetables
- grains (whole grains, such as whole wheat, oatmeal, and brown rice)
- fat-free or low-fat versions of milk, cheese, yogurt, and other dairy products
- fish, skinless poultry, lean red meats, dry beans, eggs, and nuts
- unsaturated fats
Also, you should limit the amount of foods you eat that contain saturated fat, trans fat, sodium, and added sugars.

Out of 100 teen girls who have sex, one out of three of them (about 30 girls) will get pregnant. Remember, that although most pregnancy can be prevented through the use of appropriate contraception, abstinence is the only sure way to prevent pregnancy.

More specifically, a gynecologist is a doctor who deals with the diseases and routine physical care of the reproductive system of women and girls.

"Many women consider themselves not normal if they don't get their period on the same day of the month, every month," says Mary S. Dolan, MD, MPH, associate professor of obstetrics and gynecology at Emory University School of Medicine, Atlanta. She tells them not to worry and not to expect it the exact same day of the month.

Self-esteem is our ability to value ourselves and the overall opinion we have of ourselves. People can have high (positive) self-esteem or low (negative) self-esteem. Low self-esteem can be most easily recognized by the negative statements you make or believe about yourself. Having healthy or high self-esteem means that you feel good about yourself and are proud of what you can do.
