Does emergency contraception work the same way as the abortion pill?
If you are already pregnant (even if you do not know it yet), EC will not work. EC can only prevent a pregnancy from starting; it cannot stop one that already has. And if you accidentally take EC before you know you are pregnant, it will not hurt you or the pregnancy.
