Welcome to the Board. I can't speculate why you have the growth patterns that you have. I expect that at some point it will start filling in. In the meantime be patient with the process and let everything grow for a full 13 weeks. Maybe this time around you will decide on a partial beard style like a Van Dyke or circle beard. You can also hold out for a full beard but that will take longer. Nothing wrong with that either, just be patient and enjoy the ride.

Cheers

Dare to grow the beard you were destined to have!
