I keep telling you the difference. American Staffordshire Terriers were never bred to fight. The breed was always bred to be an affectionate family dog.
Because of the way that breed looks, it's lumped in as a 'pit bull' with American Pit Bull Terriers, Bull Terriers, American Bulldogs, the American Bully, and other breeds which were bred to fight.
I am sure your dog is fine. My brother got an American Staffordshire Terrier when he was in A&M Veterinarian School. He didn’t keep it very long because it showed vicious tendencies almost immediately.. He was not as fortunate as you are. He brought the dog to my house once and it had to stay in the utility room away from the kids, I never saw it again.
