So, I have a concerning mole. I need to know if this is normal!

Tina • I am 23, a have a son. My sexual life is a mess. I work two jobs. I am looking forward to having some girl talk!
I have this mole on my shoulder, and I've never had any issues, but now it's like scabbed over... It's flaking off. But the skin is still dark underneath. Should I get it checked?
