Set up git hub local/ remote link - now bash terminal is different?

Hi, ive recently finished a section seting up a git repository on the command line through git bash, linked to git hub. But now when i open bash it opens to /usr/bin/bash? Where as before it would open to my normal PC directory C:/User/…

I write the command CMD and that allows me to travel back out of it, but without typing CMD (which changes my terminal line) if i just type cd …/… i will inevitably be stuck on the first ‘/’ of ‘/user/bin/bash’, and cant go back ant further.

IS there an explanation for all of this?

thank you for any help.
