How common are missed miscarriages?

Amanda

I am trying to enjoy being pregnant and currently 6 weeks. I haven’t had any bleeding and pregnancy test still positive, I test every week or so (I know that’s overkill). It’s just hard to wait for the first scan and mine is not until week 9. I am wondering if most miscarriages begin with bleeding or are many “missed” until that first appt? Is there anything I can do for peace of mind in the mean time? Should I get bloodwork drawn or does all that wait until scan day? Thanks
