Normal??

I had a MC a month ago. Bleeding stopped two weeks after that. Now I keep passing brown mucus and blood. It's been a week already. It's not a lot, but happens every day. Then, I had sex and I started bleeding like a period. Then it stopped again and it's back to brown almost black blood and mucus. Has this happened to anyone? I go to the dr next week, but I still wanna get peace of mind meanwhile.
