Can two parents who are both O negative have an O positive offspring?

A while back I was discussing anti-D injections
with my midwife. She told me that even though both my baby’s father and I have O negative blood groups, I should still be given the injection because there’s a small chance the littl’un would have O positive blood.
Can this be possible, even though O negative genes are recessive? (Or was the midwife just giving me a story to tell the hubbie in case I’ve been cheatin’ around?)
