It's probably ok to bottle now. But I like to wait until the beer is clear, or at least clearing. It'll clear from the top down in the fermenter, and so when the beer is clear (or clear-ish), that's the best time to start to think about bottling.
Bottling a clear beer means a better beer in the end. It means that the beer has had time to finish up, for the yeast to go back and digest its own waste products, and then for the yeast to start to flocculate out. It means less crud in the bottles in the end also.
It's not unsafe to bottle now. It's just not optimum. Another few days to a week or two longer would be better from a quality standpoint.
