Post-abortion contraception enables women to effectively manage their fertility to prevent unintended pregnancies. Using data from population-based surveys of women aged 15-49 in Nigeria and Côte d'Ivoire, we examined contraceptive dynamics immediately before and after an abortion and examined factors associated with these changes using multivariable logistic regressions. Covariates included sociodemographic characteristics, abortion source, post-abortion contraceptive communication (wanting to and actually talking to someone about contraception after abortion), and perceived contraceptive autonomy. We observed higher contraceptive use after abortion than before abortion. In Nigeria, wanting to talk to someone about contraception post-abortion was associated with increased adoption and decreased discontinuation, whereas talking to someone about contraception post-abortion was associated with increased adoption. Obtaining care from a clinical abortion source was associated with increased adoption and decreased discontinuation. Both post-abortion contraceptive communication variables were associated with post-abortion contraceptive use in both countries, whereas clinical source was only associated with post-abortion contraceptive use in Nigeria. Our findings suggest that ensuring that women have access to safe abortion as part of the formal health care system and receive comprehensive, high-quality post-abortion care services that include contraceptive counseling enables them to make informed decisions about their fertility that align with their reproductive goals.
