is it possible that there are charges under my name that I am not aware of? Will it show up under my name or the complainant's?

I lived with a roommate that I rented a room to for over a month. Things turned bad and I told her to leave. The day I told her I wanted to move out, she got vengeful and said she was going to press charges against me with law enforcement. I didn't do anything to her, so I assume she was going to make something up. Paranoid about the idea of this, I went to the police department 3 weeks later to see if I had any police reports under my name. I listed the time period in which she may have made a report, but I didn’t list her as someone involved in the report search, so I didn’t risk anything happening. They said there are no police reports for my name under this time period.
