Confusion About “Breastfeeding Exclusively”?

Maybe this is a dumb question, but I’m a bit confused about the exact definition of “breastfeeding exclusively”. Like I plan to give my baby breastmilk only (no formula), for at least the first 6 months, but if I want to give her pumped milk every once in a while, am I still “breastfeeding exclusively”?
