Answered by The Community. Making the world better, one answer at a time. Teenage pregnancy not only affects a person emotionally, but also physically, mentally and financially. You may experience mood swings and feelings of guilt and sometimes even regret.lthough, some teenage girls do fine on their own, it is very likely that they need support for their parents or others or do not do very well. To prevent teenage pregnancy condoms & birth control & other protection is highly recommended. If you or someone you know is in this situation, adoption may be the right choice.
