Sick call question:

If you have, lets say, 6 reserve days on (A6 window), and you call in sick for one of those days before the 90 minute call window begins, is it considered a day off in determining 1 in 7 if scheduling wants to move a soft day that falls on day 7? I was not able to find any answers in the contract as to whether or not a sick day counts as a day off if you call in before your assignment window starts.
