It's been a week since I m/c

I was told last week, after starting to bleed on Sunday, that I was having a miscarriage. I was about eight weeks but the sac measured to be 4-5 weeks along. I'm cramping and still bleeding today, marking one week since I started. How long does this process take to complete? I don't see my md again until next Thursday to make sure everything is cleared out but I didn't think it would take this long since it was just the sac found. There was no baby detected
