OG stands for original gravity, the specific gravity before the yeast have had their way with it. If you are brewing using extract and have your quantities correct, this is the gravity you will have regardless of what your hydrometer says. It's really common for those who use top off water to show a different OG. This is because the wort is very difficult to get mixed properly. Don't worry if it happens, your major concern would be that the beer ends up totally fermented out and you check that with the hydrometer.
