When did you launch? Weddings are generally pretty seasonal, so I would guess you'll get a lot more traffic in the next few months. Also, is anybody linking to you?
I first made Knot News public last September, though I didn't really have a launch. I managed to get a handful of wedding blogs to post links to Knot News at the time, which is how anybody knows about the site. Today, most of the traffic I get is direct or from Google searches for "Knot News" or something similar. I've been trying to get all of the blogs that are covered on Knot News to link back to Knot News, but it's a slow process.
The wedding industry is huge - planners, photographers, musicians, florists, etc. If you can get these people to link to you, you'll start to do better in organic searches.
