Between A Pill and a Hard Place
Too much estrogen and you end up with blood clots, too little and you end up with pregnancies. What's a contracepting woman to do?
According to CNN, the FDA is concerned that recent efforts to make the pill less harmful have also made it less effective, and are considering new regulations to ensure that FDA approved contraceptives do indeed block conception.
Of course pro-lifers have pointed out for decades that contraception is closely linked with abortion, by virtue of the fact that no contraceptive method is 100% effective. The recent FDA discussion definitely lends credence to this argument.
