Does this sound like a missed miscarriage?

I’ve been having brown spotting/discharge for almost 2 weeks now. I’m 7 weeks 3 days. It’s mainly when I wipe but if I wear a liner, I usually get something on that too. I just learned about missed miscarriages and am now afraid that it could be what’s happening. My ultrasound is next week. I don’t really have many symptoms, I was tired and a bit nauseaous before but the symptoms wearing down has me worried. I also still get dye stealers so I don’t know what to think. What do you guys think? Could I be miscarrying?
