Miscarriage at 5 weeks

Hi ladies,

I was 5 weeks pregnant when I started bleeding( doctor said Im having miscarriage)...first 3 days heavy bleeding with clots ( sorry for tmi ) then light bleeding ( red ) then for few day brownish and then red again. 11 days today since I started bleeding. Does it take so long?? I was only 5 weeks. And still positive pregnancy test but the line is not as darker as before I start bleeding. Called my doctor and he is sending me for a scan tomorrow morning. I’m worried why bleeding takes so long 😔 anyone had same experience?
