There is a prevailing, old-fashioned belief that one can't get pregnant while breastfeeding. Although breastfeeding may reduce a woman’s fertility, it does not prevent pregnancy. Although new mothers usually do not ovulate before three weeks after giving birth, and a mother may not menstruate for months after giving birth, there's no way to ensure or predict exactly when her body will release its first postpartum egg, and she won't know until roughly two weeks after ovulation.
