"I know my body and I just can't get pregnant that easily" - Women's use and non-use of the injection to manage fertility.

Approximately one-third of contraceptive users in Malawi use the Depo-Provera injection, a method that must be re-injected every three-months to prevent pregnancy and may reduce fecundity for a time after discontinuation. Little is known about women use the injection to achieve their desired family size. In 2018, we conducted 20 in-depth interviews with women who were part of a cohort study in rural Malawi. Interviews focused on contraceptive decision-making. Data were indexed (summarized) and coded using narrative, process, and thematic codes. Women described the importance of knowing about their "natural" fertility by having children prior to ever using contraception because women considered contraception to have a potential negative effect on fertility. Women then applied what they learned about their fertility (i.e., how easy/difficult it was to become pregnant) to manage their fertility over their reproductive life-course. As part of fertility management, women frequently described using the injection less frequently than clinically recommended, using signs from their body (e.g., menstruation) to determine when to reinject. Managing fertility through subclinical injection use was viewed as a way to optimize women's' chances of preventing unintended pregnancy while maintaining their ability to become pregnant when they wanted to. Women wanted to play an active role in managing their fertility and were not passive consumers of contraception. It is therefore critical that family planning programs provide contraceptive counseling to women that engages their desire to manage their fertility, acknowledges their concerns about fertility, and helps them choose a method that best fits their needs.
