Police

No. Until you're 18, Mom and Dad basically own you and can file charges on your behalf if they want to.
You should file those charges immediately. If you wait, the court will wonder why you waited if the situation was serious enough to file charges. You will not be taken seriously if you continue to live with or spend time with the abuser before filing charges. You should have filed a police report immediately and the police would have taken photos. It is puzzling that you would want to wait to press charges. The longer you wait the less attention you will get.
The Government can file charges instead of the police in certain cases and if there is enough evidence to file charges.
