Welcome!
I don't think you should stop, I think you should maximize what you have by growing it for like 6-8 more weeks!
I am 140% sure that things will look thicker with more time and hair length.
From what I can see you have a good chin growth going on there, so I would definitely say keep a goatee at least.
Nevertheless, you should keep growing for 2 - 3 months like patrick said, it will help you to see what you actually have.
The other areas will fill in with more time, just relax and enjoy your journey to beardness!
