I've been having this weird discharge and smell?

The past couple days I've been having this really weird smell down there. It's not fishy, so I'm pretty sure I don't have Bacterial Vaginosis. It's metallic at times, but other times its just foul and indescribable. The discharge hasn't changed in color; it's still clear. It's just been really watery lately, and randomly a lot of it will come out. It sort of feels like I've gotten my period. There's been no itching, burning, or anything like that. What could be wrong with me? Is it some sort of bacterial infection?
