At this point your beard is in full development and you will see new terminal hairs every month from here until all the follicles are growing.  That could take a few months or a few years or longer.  The question for you is how much coverage you need before you let it show.  I am in favor of letting it grow for the next few months to see what you have to work with.  You will have a fullbeard before you know it.

You probably will have a challenge with parents as you get even more bearded at this age.  I suggest you just keep saying how much you like and want this beard... stay away from arguments about it... keep it to how you feel and don't try to convince them to like it.  Eventually, they will get on board and be more supportive.  Keep humble about your accomplishment and supportive of those around you.  They will be jealous but you can also encourage them without boasting about your beard.
