I doubt that downward trend has continued (bet it's at least slowed) for the general population, I can't imagine sex ed has gotten any better nationwide. But I don't have any newer sources at hand either.
The Affordable Care Act providing free birth control did not even kick in until 2011. Between that, increased access to healthcare and doctors in general due to ACA, and access to more information due to proliferation of internet and smartphones, I would guess more women opted into birth control over the past decade.
