Title: Breastfeeding and Oral Contraceptives: a Randomized, Controlled Trial
Brief Summary: Objectives

To clarify the relationship between postpartum (2 weeks) use of progestin-only vs. combined oral contraceptive pills and the outcomes of breastfeeding continuation, infant growth, contraceptive method continuation, and pregnancy rates in breastfeeding women. Specific research questions:

1. To determine whether there is a difference in rates of breastfeeding continuation at 2 months and 4 months between postpartum breastfeeding women using progestin-only pills vs. combined pills.
2. To determine whether there is a difference in infant growth at 2 weeks and 8 weeks between postpartum breastfeeding women using progestin-only pills vs. combined pills.
3. To determine whether there is a difference in birth control method continuation at 2 months and 4 months between postpartum breastfeeding women using progestin-only pills vs. combined pills.

Hypothesis

Combined oral contraceptive pills, when initiated by postpartum breastfeeding women, will cause a differential in continuation of breastfeeding: 35% continuation in the combined pill group vs. 60% in the progestin-only pill group at 8 weeks.
