Is the combined oral contraceptive pill (OCP) contraindicated in women who are breastfeeding?
No. As a rule however, oral contraceptives should not be started until after lactation is well established (usually 6 weeks post-partum). This is because the use of oral contraceptives may diminish the quality and quantity of milk in the post-partum period. No adverse effects of contraceptive steroids secreted into breast-milk have been identified in the baby.
