It should be cloudy, that's a major part of the style. The yeast will take quite a while to drop out.
As long as by "cloudy" you don't mean "chunks of goop" or anything gross, you should be fine. Clearing it would require lots of time or a filter, and make it a different style of beer. It will clear a bit over time, but don't avoid drinking it because of that.
I'd start drinking as soon as it's carbed and tastes good, hefe's are meant to be drank cloudy & young.
