In published studies, hormonal contraception (HC) has not been found to affect breastfeeding outcomes. However, early introduction of exogenous progestins may inhibit or prevent adequate breastfeeding in some women. We sought to estimate the proportion of women who perceive breastmilk production to be affected by hormonal contraception by conducting an anonymous, Internet-based survey of adult postpartum women regarding their experiences with postpartum events, including initiating contraception, resuming intercourse, and breastfeeding. The survey was introduced via social media, listservs, and websites. From January to May 2016, 2920 women completed the survey and met inclusion criteria. Milk supply concerns occurred in 1044 (37.6%) of participants in the first 12 weeks postpartum and were more common among HC users than non-users (42.5 vs 35.5%, p<0.01. Understanding the complex relationship between hormonal contraception, breastfeeding, and other events in the postpartum period is essential to providing care for lactating women.
