AG or Extract? (You said you are a newer brewer - so I'm going out on a limb and guessing extract here).
If you did extract and topped up, but didn't stir all that well, then you probably had stratified wort (e.g. - layers in the wort) and you pulled your sample from the heavy part that wasn't uniformly diluted yet. This is a pretty common newbie "mistake".
If so, relax, it will mix up just fine in the fermentor. It's pretty much impossible to miss gravity on an extract batch since all the fermtables make it into the kettle unless you totally mess up your volume.
