Nope, you're looking good. Normal, healthy fermentation for most beers completes in about 3-10 days, depending on the yeast and beer in question. Is the first gravity reading you've taken? Wait a couple of days and take another. If it hasn't changed, then fermentation is complete.
At this point your beer has achieved 85% attenuation, which is a little on the high side to my mind but I've never worked with US-05 before. A quick search of the Internet shows that 85% may be in the normal range for this yeast. Your beer may be a bit on the dry side. If the beer tastes good, then no worries.
