Am I going bald?

M26 started growing out my hair for the first time. I am in year 2 and I can't help thinking I'm going bald. I have an afro with I think 3C-4A hair. I keep it in a dew rag when pretty much everyday and wash it every 3 days and keep it moisturized. I take biotin BTW. The club of hair is from not washing my hair for 4 days. 1st pic is when wet, 2nd pic is when towel dried, and 3rd is when I have it tied back with conditioner in.
