How long did you bleed with early miscarriage &

And also how long did it take for the hcg to go away and show a negative test? It's been 28 days of bleeding and it's still showing a faint positive test.. I was like 3 weeks pregnant when I started to miscarry. I've been bleeding awfully long for a early miscarriage... Thanks in advance for the comments !!
