As long as you can contact this girl your ok. Have her go get a morning after pill and go with her to ensure that not only she goes but to comfort her. It can be scary ( Ive been in this situation). It works best within 24 hours but is still effective and can be taken after 72 hours, so get it on a.s.a.p!! I had to go to a local clinic first and be checked out by the doctor and then they will perscribe the pill.
