Yes. Breastfeeding may decrease the odds of getting pregnant by delaying the return of a woman's menstrual period. However, breastfeeding does not prevent pregnancy, even if the mother is not getting a period. Many women ovulate before they see their period return. If you want to be certain not to conceive again until you and your partner are ready for another child, talk with your health care provider about when to return to using birth control
. Note that some oral contraceptives that contain estrogen may decrease a woman's milk production. If you think this might be a problem for your milk supply, discuss different birth control options with your provider.
