Postpartum contraception: A matter of guidelines.

The postpartum period is the perfect time to access family planning services. WHO guidelines contraindicate combined hormonal contraceptives postpartum in breastfeeding patients between 6 weeks and 6 months after delivery (Medical Eligibility Criteria category 3). On the contrary, the Faculty of Sexual and Reproductive Healthcare and the Centers for Disease Control and Prevention guidelines do not contraindicate their use in women who breastfeed from 6 weeks to 6 months postpartum. New combined hormonal contraceptives with natural estrogens have never been studied in this setting. Guidelines agree on the prescription of the progestin-only pill postpartum in non-breastfeeding women (category 1). Differences are found in women who breastfeed. In non-breastfeeding women, an implant is considered safe (category 1) by all guidelines, without any distinction in time. Regarding postpartum breastfeeding women, the guidelines for implants give quite different indications but are still permissive. Intrauterine devices are viable options for postpartum contraception but guidelines give different indications about the timing of insertion. Postplacental intrauterine device placement can reduce the subsequent unintended pregnancy rate, particularly in settings at greatest risk of not having recommended postpartum controls. However, it has yet to be understood whether this approach can really have an advantage in high-income countries. Postpartum contraception is not a 'matter of guidelines': it is the best customization for each woman, as early as possible but at the ideal timing.
