First, you should keep it in for at least 2 months before you start removing it every so often to clean it better. It will get infected, sometimes it'll emit a slight smell, and will stay red, but just keep cleaning it *constantly*. It shouldn't last more than a month though. Use anti-bacterial soap (non-scented, it could increase a chance of a bad infection) or hydrogen peroxide.
Also, always keep it as tight as possible to prevent it from falling out.
I got my eyebrow done and my gf got her labrae done. It didn't go well for me. The dude who did it not only pierced mine at an odd angle (near vertical, it should be a slight bit slanted) as well as using a small bar. A few days after I got the thing, the bar slipped out one morning in the shower, and the piercing place wasn't open as early as I was up. By the time I went to get it done again (about 3 hours later) it had sealed, and the regular artist pierced it at the correct angle, almost crossing the other pierce. The aggrevation of the skin and me having to remove it for work finally resulted me in pitching the thing - it wasn't worth it.
So I guess my long-winded point is (and I realize you got your ear done, so it'll probably be less of a problem) don't remove it, keep it tight, and clean it every 2-3 hours for the first week or so.
