Possibly.
How long has it been since you pitched the yeast?
Primary fermentation generally lasts around 5 days, but it can run shorter or longer than that depending on a number of factors.
It may just be that fermentation has not finished. I would wait three days, and then take another gravity reading. If your SG changes, let it sit a couple more days further. If your SG does not change over a 3 day period, then your fermentation is likely complete.
