Anybody else have this at 7 weeks?

On Saturday I noticed some brown spotting when I wiped.. It continued until last night and now it's barely there. I haven't been "feeling" pregnant (boobs are sore but that's about it) but I took a test last night to see what it would say and it still said pregnant. My dr won't get me in until my regular appointment next week and I'm freaking out. Anybody else have anything similar to this and had a great outcome? I had a miscarriage before and my signs started out as brown spotting so I'm a little nervous. Any help would be appreciated =)
