A nationally representative cohort of 2863 French women was studied to identify 272 instances of EC pill use. In 71% of the cases, we found no changes in contraceptive practices from the time of EC pill use to 6 months later: 41% of women continued use of highly effective methods and 30% continued less effective methods. Only 8.4% switched from highly effective to less effective methods. %G English %L inserm-00382097 %U https://inserm.hal.science/inserm-00382097 %~ INSERM %~ UNIV-PSUD %~ INED %~ SANTE_PUB_INSERM %~ UNIV-PARIS-SACLAY %~ UNIV-PSUD-SACLAY %~ CONDORCET4 %~ CAMPUS-CONDORCET
