That simply isn't true, not in cases involving pregnancy.You are still missing the point. "Teen" girl can do whatever she wants .... as long as she is 18!
17-13 year old "teen" girls cannot make medical decisions for themselves. It is by law still the responsibility of the legal guardian.
If abuse or potential abuse is suspected, then contact the appropriate authorities and that would not be an abortion clinic!
and if it were, what would happen in the examples I just gave?
