Vaginal discharge and smell

Lakota

I'm very embarrass to say, but my vagina is suddenly super smelly. Not like a gross fish smell but like, I dont know. It kind of smells like the smell you get behind your ears? When I take my finger to check my IUD or to ich, my fingers smell soo bad. My vagina has never smelled this way ever.. what could it be and how can I get rid of it? Please help.
