Pumping at work policy

Can anyone tell me? Prior to nursing I never ever took breaks so I’m probably overthinking this…. My company policy is 2 15 minute pumping breaks in a day for one year. But technically I’m entitled to 2 breaks in a day anyways right as a full time employee? So I should be able to continue pumping until my baby is weaned here in a month or two right?? They don’t need to know what I’m doing on my break.
