Baby Mama Drama

Hi guys, I was at work today and I was sitting in my car and all of a sudden this car pulls up to me. This lady gets out she walks up to my window she starts accusing me of sleeping with her baby daddy. I am currently not seeing or sleeping with anyone, I told her that she did not believe me she kept saying that I was messing around with him, yelling at me, calling me names. I have never seen this woman before in my life. She says that she lives in the same apartment complex as me gave me the name of my apartment complex so I know she actually does. She says that I work with her baby daddy and she told me his name I’ve never heard the name before. Don’t know who she’s talking about. She said she’ll be watching me. I just feel unsafe at my home and my place of work. Does anyone have any advice? Should I file a police report or is that overdramatic?
