hydrometer readings are very important. They will tell you exactly what's happening with your brew. For example if you were not to sample and got a stuck fermentation and just bottled at 2-2.5 weeks there is the possibility that you wold end up with a bad brew at least and bottle bombs at worst.
If you want, just leave your testing until the 10 day mark, and then test again three days later if you get consistant readings on the 13th and 14th day, I would go ahead and bottle (this is presuming that you are not using secondary).
