Help me out girls!

Mallorie
So today I was getting in the shower and I took off my panties and caught a nasty whiff of something. So I usually have normal discharge and it changes depending on the time of the month, but this is unlike anything I've ever smelled before. It didn't look unusual though. I just went to the bathroom and I have some light spotting, but I'm not supposed to start my period until next week. Help me ladies!! I'm slightly freaking out but I think it might just be BV.
