I seriously can't believe it's 2009 and people are recommending pulling out as an effective birth control method.
She can actually go to Planned Parenthood and they will give her birth control for free and her parents won't ever know about it. She gives them her cell phone number, they never identify themselves to anyone other than the to the person they are calling and no prescriptions are involved since they just give you a couple months of supply when you're there. She can hide them in her house and take them daily. That's why places like this exsist, but please, still use a condom. Don't risk it.
