Key / Solo question...... Part 1

Question 1....
I am playing Bm, Bm, G, A.

I was looking in the key of B (B, C#, D#, E, F#, G#, A#)
But clearly G is not in this key (G# is but thats not what I am playing)

So am I playing in the key of C, G, or D??? All of the notes Im playing are in those keys (B, G, A).

You're playing in B minor. The chords in this key are: Bm, C#dim, D, Em, F#m, G and A.
