You should not be "anxious". Your beard is just starting to grow which is normal for a 17 year old. It should continue to get better over the next few years. I do not think you are ready to sport facial hair yet, however. I would shave until your growth gets a little better...perhaps in a year or so give it a try.

Patience shall be rewarded!
