using several git programs simultaneously

[Name of Mine]

I have a question of a basic nature that no tutorial has been able to answer to me. I was working with SourceTree in a local repo pushing to Github.com. At some point I decided to use Github Desktop, so I added the local repo and started to push to Github.com. I did not like this software, so I went back to SourceTree. Opened my project there but changes were not being tracked anymore. I wonder if one can use two git managers for tracking changes or else I don't know what went wrong.

I have no experience with either Github Desktop or SourceTree. Sorry.
