What are five risks that girls are exposed to by falling pregnant?

(Not exactly sure what you meant by 'falling pregnant' but I'll try to answer anyway) Adolescents who have sexual intercourse are at risk for a numerous amount of harmful STIs and/or STDs. They could be exposed to unwanted bacteria or infections. They are at risk for an early/unexpected pregnancy and health risk factors. Pregnancy risks are birthing defects, irregular periods / the menstrual cycle stops during pregnancy. Alcohol and drug use can harm an unborn child if used during pregnancy. If the girl was unprepared for her child she could run into family trouble, financial trouble etc. I hope this answers your question.
