This is a retrospective cohort study evaluating the effectiveness of early medication abortion between 64-70 days gestation in the UK using a mifepristone and vaginal misoprostol regimen. This study will be performed in collaboration with BPAS, whose abortion data specifically for this gestational age is impressive, with over 2700 cases of early medication abortion. This study will help determine the effectiveness with larger numbers than previously described in the literature.
