First Dr. Apt?

So I will be 5 weeks tomorrow and I just called my dr.’s office to schedule my first appointment and they wouldn’t make one until I was 10-12 weeks along EVEN though I had a horrible miscarriage in June and they where aware of that. They said all I could do before that was blood work. I see other people on here getting scans at 6 weeks. What’s the deal?!?
