Tabitha M. Powledge discusses the state of the science on whether certain birth-control methods prevent implantation: "The scientific consensus is … that nothing happening before implantation can be considered abortion because there is no pregnancy until after implantation. Unfortunately, that declared scientific consensus is seriously undermined by the fact that the FDA-required labels on these birth control methods warn that they may prevent implantation. Ooops."
