Not sure what's going on..

So the past couple days I've thought I was slowly losing my mucus plug, I'd go to the bathroom and wipe and there'd be a little bit of discharge that was white/light greenish color and kind of eggy..everything I've looked up said that it was probably me slowly losing it. But I know that doesn't always mean that labor will follow right away. But I noticed yesterday and even more today I now have a smell down there.. /:  :S I don't have a yeast infection or anything. 
Could losing my mucus plug and a smell following it mean labor soon? Or...??
