This combination hormonal contraceptive (CHC) system has not been specifically studied, however studies with segesterone implants have detected exposure to the breastfed infant.

Expert opinion recommends against use of combined hormonal contraceptives for the first 3 weeks postpartum due to increased risk for venous thromboembolism; women with other risk factors for venous thromboembolism should avoid use for 4 to 6 weeks after delivery. The World Health Organization guidelines recommend against use of combined oral contraceptives before 42 days postpartum and suggests that that the advantages of use between 6 weeks and 6 months postpartum is generally outweighed by risks.
