Like biondino said, it's probably fine to stay where you are for microstakes.

Play $2 SnGs if you like tournaments, play the microstakes cash if you wanna play that. When I first started playing poker, I played SnGs because I liked them. You will have no problems building up no matter what you play if you stay within the BR requirements, post lots of hands, and keep trying to improve your skill. Build a bankroll and have fun at the same time!
