Probably not. If you used all the extract and the right amount of water, then it is impossible to "miss" your SG like you can when brewing all-grain. The "set" amount of sugar in the extract, and the "set" amount of water mean that you cannot mess it up. It is very common for the extract to not fully mix with the brewing water and cause gravity readings that are WAY too high, or WAY too low. If your sample was mostly water with the extract not fully integrated, then the reading would be extremely low (like your reading was). Sometimes people have the opposite problem, and the gravity sample is mostly extract with not enough water incorporated into it. This causes SG readings that are ridiculously high.
Pitch your yeast, control fermentation temperature, and enjoy your beer. It will most likely turn out just fine!
