What's the rotations I should run as a low level rouge?

I'm a level 28 Rouge, and I've never played WoW before, the concept of Macros are very new to me and I just know what I'm running now isn't as efficient and damaging as it could be, so I'm asking the community what my rotations should be as a level 28 rouge who's speccing mainly combat.

-Currently-
Main Hand - Sword
Off Hand - Dagger

Rotations : Sinister Strike > SnD > x5 Sinister Strike > Eviscerate; repeat.

I don't use anything with stealth, because when I'm leveling I can kill these things alright so an opener isn't what I'd think i'd need.

Thanks for the help!

use garrote and rupture and crippling poison for kiting'

Your rotation is alright. Regarding openers, you would still want to use Garrote or Cheap Shot - the bleed from Garrote helps a lot and the time from Cheap Shot allows for a nice setup and kickstart before the mob can turn to you.

Cheap shot should never be in ur roration for leveling rogue it takes way 2 much energy for nothing if ur sub go for ambush first if ur anything else just start with ur main combo gain ability which should be sinister strike and thats it.

Well, it's a 4-seconds stun during which you can make a setup with Slice and Dice, for example. At the time Cheap Shot is over, the mob will already be on 2/3 HP and you'll still be full - that's its advantage. Garrote/Ambush's advantage is just a faster kill overall. Personal preferences.
