Just leave it be. Stop taking the lid off. Throw the instructions in the garbage. The bubbles mean nothing. The only way to see if it is fermenting is if the Original Gravity is dropping. You can tell by buying a hydrometer and taking a hydrometer reading. Funky smells means your yeast is working. That smell is leaving your beer thus why you are smelling it. The yeast is cleaning up after itself.
Now if you keep messing around with it you could ruin your batch. Each time you open the lid, you risk introducing wild yeast, bacteria, oxidation, and other nasty things.
Did you sterilize all your brewing and fermenting equipment well? Did you brew at the proper temps? What is the temperature your beer is fermenting at? These things are important. If it is fermenting at too high a temperature, you could be messing up the process.
Also if you want help, we need to know more information too. IE what temperatures you're wort is, etc.
One of the most common causes of the egg smell is stressed yeast, usually caused by extreme fluctuations in temperature. You may have pitched your yeast when the wort was too hot. Your fermenting temps should be idle. So again, information is key. You should probably read a book on brewing so you understand the science behind he process. Then you'll understand that temps are key to the process. Good luck!
