Need urgent help. Bleeding. plz help.

I discovered i ws  5th week pregnant in july 2018. But it ws a hydropic fetus and its heart stopped beating in th 13th week of pregnancy. This ws my third miscarriage. I ws v disheartened. I went fr a D & C on 8th sep. After my d&c bleeding did not stopped so my dr said dat something is still left in my uterus so she prescribed me to take mesoprost 200mg virginally. I bleeded heavily with clots. Still bleeding did not stopped. Again after 2 weeks my dr said sum tiny bits are still left in my uterus. Again i took mesoprost. Again heavy bleeding with clots. Still bleeding did not stopped. Dr suggested another D&C. On 11th oct hd another D&C. But bleeding still did not stopped. Dr prescribed Crina NCR for 20dy. By dis time i hv become very exausted and frusted. Dont understand if some negligence have been made by the dr.. i went to new dr who have prescribed medicines and injection placentrex. Still dont knw it will help or not. It have been two months bt still bleeding.. plz help.
