This might legally be statutory rape (in the US). It depends on the Age of Consent in the place where you live and on the age of the father.

Two things we can say right away though is that you can not move out without parental permission and if sex is not legal in your state at your age, it is still not legal eventhough you are pregnant.
Why is a fifteen year old even trying to have a baby? Keep it in your pants!
There could be charges against the adult. The boy shouldn't be an issue.
