American women are changing up their birth control. The use of IUDs and implants has increased 6000% in the United States since 2002.  That's the result of specific policy choices made in Washington and in state houses. These policies have reduced the teen pregnancy rate. They have cut the abortion rate. But they’re also at risk right now.  In this episode, we’re going to tell you how those policies came to be, how they're helping women access birth control -- and why, at this very moment, they are facing serious threats.
