What Does Prolonged Bleeding After Miscarriage Indicate?

Prolonged bleeding after miscarriage ? I had light spotting week of August 20th and finally went to the hospital on August 26th because spotting was getting heavier , I was suppose to be almost 11 weeks pregnant but an ultrasound revealed my baby passed at eight weeks. Doctors dx it as incomplete miscarriage and told me contact my obgyn in morning for a referral to specialist for d&c. I contacted my obgyn but instead of referral she sent me for blood work to only check my hcg levels. She said I should miscarry on my own. The levels came back not much lower than hospital bloodwork so again more bloodwork was ordered days later. ALL this time later im still ( 8 weeks ). For the last two weeks its off and on at times just running out of me , its more ON than off but I do get a two hour break before bleeding again but everytime I think this nightmare is finally over it starts right back up again. I ve had blood work seven times with my last blood work being two weeks ago and I was told my levels were at 22. Ive questioned the bleeding repeatedly and was told that once my levels reached zero the bleeding would stop but it hasn t. I m extremely upset that I am still going through this all this time later , I m upset cause I feel like my obgyn doesn t know what she s talking about and im upset that she made the decision for me to spend the last eight weeks of my life suffering. I feel drained to be completely honest and weak. This wasn t my first pregnancy it was my tenth , I have five children , this was my fourth miscarriage , my first pregnancy was a forced abortion unfortunately , my last miscarriage was in February of this year and I got pregnant again immediately just to miscarry. Im in my early thirties , and am anemic , is it possible that has something to do with this ? I just want this nightmare to end. Please help me , Thank you
