Bleeding after months of abortion (D&E)

Hi, I am 26 yrs old and had 2nd early pregnancy loss 2 months back. Doctor has done D&E on 28th May and gave me Misoprostol (miso 200) to clear the remaining part, I had continue bleeding after a week so went again and she had repeated the Misoprostol again for 2 days as she see some part still remains inside.. After e weeks i started observing spotting and it is continued. I checked with another doctor on 4th week and scanned myself, doctor confirmed that it seems to be normal and he started contraceptive tablet for next 3 weeks to regularise the cycle. But during this period I observed the bleeding intermittently, I also tried with Pause 500 but not stopped completely. Now its almost 2 months and i still bleeding and experiencing pain in my lower part. As per doctor my periods should come in next couple of days as the contraseptive dose of 21 days just completed but I am worried a lot. What should i do next it should not lead to any new problem.. could you please help..
