Hey My Name Is David, And My Girlfriend Was Raped

Hey my name is David, and my girlfriend was raped when she was about 8 years old by a boy who was at most 13. She went to the doctor to see if she has an STD ,she asked durring a yearly checkup. She's really loosing her mind and doesn't know what to do if she does have one. She's never shown anysighns of a major atd like herpies or aids or hiv. But I figured to ask a expert on the matter. What kinds of STDs could she have and what are the sighns. And how could they effect the rest of her life?
