If it's still actuating the clutch, then there is still fluid in there. It's probably just overfilled so you can't see a bubble. I just checked and I don't see a bubble in mine. If you're really worried, you can check by unscrewing the two phillips screws on the top of the reservoir, and pulling out the rubber bladder.
You wouldn't need to bleed if you're just adding fluid and no air got into the master cylinder. Having hydrated clutch fluid isn't as bad as hydrated brake fluid, so I wouldn't be too concerned about opening up the system to check the level.
Of course, your other option is to stop using the clutch all together. I think there is a pretty big consensus that that is smoothest and when properly done will not damage the bike.
