Pregnancy is the physiological process of the development of the fetus in the mother's body, as well as a completely new physiological state of the woman's organism, which is accompanied by numerous anatomical and functional changes, and can represent a major turning point in a woman's life, especially if it happens to a girl under 18 years old. Premature sexual relations in adolescence are the most important factor in the high rate of underage pregnancies, which is confirmed by the results of numerous studies, so the average age of young people in Croatia who enter into sexual relations is between 16 and 17 years old. Adolescent pregnancies are often unplanned and uncontrolled and, accordingly, require special care and attention. In addition to premature sexual relations, there is often pressure from family and society to get married, as well as various forms of violent behavior, which ultimately results in dropping out of school and lack of education. In accordance with the mentioned problem and risks, the support of family, community and partners and the development of new strategic and educational programs, as well as the involvement of numerous organizations and institutions for the support, development and counseling of young people, are certainly indispensable.
