It's not going to work. And here's why.
In the U.S., teen pregnancy is primarily a problem in religious societies, particularly among Catholics. Normal people like you and I allow and approve of sex-ed, condoms, abortion in the first trimester if it comes to that. Religious zealots do not approve of any of it. Their standard answer is "abstinence till marriage". And, of course, it fails. It fails so bad that teen pregnancy rates among latina girls (for the most part, raised in zealous Catholic households) can be literally TEN TIMES higher than those of godless white residents of Silicon Valley.
You can have the best available kinds of contraception in the world, and they won't help if the only thing that the teen's parents would accept is abstinence till marriage.
