give it some more time, and don't worry about smell. give it another week ,take a gravity reading, and taste your sample. fermentation can sometimes smell good, other times smell horrible it doesn't mean anything is wrong.
Fermentation is ugly and stinky....and that's when it's perfectly normal...like now. Look up "rhinofarts" on here and you'll know...or even lagering, and why folks lager.....
The smell is likely H2S which will dissipate over time in the primary. I just went through the stinkiest primary in a while a few weeks ago - and now the beer is divine.
