As long as the gravity had stopped dropping (three consecutive days of the same SG), and as long as you didn't add too much bottling sugar (plenty of calculators around) there's virtually no chance of bottle bombs, barring glass defects.
You'll just have a little extra kick in your brew (assuming a temp of 65 for both measurements, about 5.3% ABV) but that's hardly a bad thing.
