Teenage pregnancy is defined as a pregnancy in a woman under 20 years old. It can be caused by early marriage in some cultures where it is seen as proof of fertility. In other societies, lack of education about contraception and pressure to have sex can lead to unintended teenage pregnancy. While most teenage pregnancies in developed nations are unplanned, some teens deliberately get pregnant. One way to address this issue is through a public awareness campaign that informs teens of the responsibilities of pregnancy without telling them to abstain from sex, encouraging them to think about what they really want for their future.
