Whats going on down there

I have a discharge that has an odd odor but nothing else. No itchiness no pain while urinating no cramping nothing just an odd odor and some discharge through out the day it's not a lot even just enough that i can feel it in my underwear. I don't want to go to the Obgyn if it's nothing. It's been about 2 weeks i was gonna make an appointment the other day but it had stopped for a couple days and now it's back. Any ideas?
