Prolonged bleeding 7 weeks

Hi, I had a very heavy period soaking through my pjs several times a night hospital gave me tablets to help stop the bleeding. They gave me a smear test and I tested positive for HPV and abnormal cells I had fallen pregnant after this and suffered a miscarriage. This was 7 weeks ago and I haven’t stopped bleeding since. I have been for a colposcopy and they have taken 3 biopsies. I am waiting on results but still bleeding my bloods have just came back low ferritin. I am really tired and struggling at work as my job is physical. Has anyone had bleeding this long and what was your outcome etc? I have had internal and external scans of womb and ovaries and it was all fine doctor said it isn’t miscarriage related.
