I wouldn't worry too much Julie, in the grand scheme of things it's not a problem.
You've been using it as a B choice, a B choice is usually around 6 syns. You've had 5 syns with your bread.
Okay,so technically it wasn't an "official" B choice but you haven't gone over on your syns chick. Don't worry, just use an official one from now on.
You will be fine!
