A pregnant client tells the nurse they would like to begin a birth control method immediately postpartum and asks what options are available. As part of the education session the nurse would counsel the client that which of the following methods are contraindicated in the postpartum period? Select all that apply

Rationale: A. Progestin-only pills are safe and commonly recommended postpartum, especially for breastfeeding mothers. B. Combined oral contraceptives contain estrogen and are contraindicated postpartum due to increased risk of venous thromboembolism. C. Contraceptive implants (progestin-only) are safe and effective postpartum. D. Contraceptive patches contain estrogen and are contraindicated postpartum because of thrombosis risk. E. Contraceptive rings contain estrogen and are contraindicated in the immediate postpartum period for the same reason. F. Contraceptive injections (e.g., Depo-Provera) can be associated with delayed return of fertility and possible bone density concerns, but generally are used cautiously; some guidelines advise caution or delay in administration postpartum due to thrombotic risk, especially in breastfeeding women, so they may be contraindicated immediately postpartum.
