I don't know if it's "birth control" but it will definitely let you know that "Plan B" is not considered "pregnancy-termination" it is still legal in all States.
i'm confused what this is in reference to, but yes, levonorgestrel emergency contraceptives can't be called pregnancy termination by even the most extreme definition because it works by delaying ovulation, does not impact implantation and does nothing during/post ovulation/ and 'conception'
