Study Summary

We are studying the effect of placing the levonorgestrel IUD (Mirena) immediately after birth on breastfeeding. Women who wish to have a levonorgestrel IUD placed after their birth, wish to breastfeed, and are willing to participate in the study will be randomly assigned to either get the IUD placed immediately after delivery of the baby and placenta or 4-6 weeks later. We do not believe there will be a difference in breastfeeding 8 weeks after delivery between those who get the IUD placed early or later.

Primary Outcome

To determine breastfeeding continuation rates at 8 weeks in women randomized to immediate post-placental vs. delayed (4-8 weeks) postpartum levonorgestrel IUD insertion.

Interventions
