Not quite. Some of us do not ovulate while breastfeeding.
HOWEVER. Not only is it impossible to know if you are in that group beforehand, some women who did not ovulate while nursing their first child do while nursing a later one (given that each baby has different nursing patterns, this is hardly surprising). Nonetheless, for some women, breastfeeding alone can prevent another pregnancy.
Certainly not something I would rely on if it were important not to get pregnant, though.
