loud noise

So my clutch gas been slipping but I had to drive my dart anyways so I took it slowdriving about 45 min. I get to my destination, park, then turn the motor off. As I do it I hear a loud noise like someone threw something at my car. Nobody was around and I could tell where the noise came from. So I got back in started the car and it sounds fine. I backed it up a few feet then drove it forward. Seems fine but I haven't really drove it since I got to my job.
Could something have shot into my mouffler from the engine and I just don't know or idk. Gonna be iffy about driving it home smh
