Pregnancy with IUD

Hello everyone! I have had a paraguard IUD for 6 years recently experienced brown discharge (looks like old blood). Took several pregnancy test all of which show positive results. I went to my Gyn. Who checked that the IUD was still in place and also decided to give me a pregnancy test which also came back positive. She removed the IUD but now I have more of that brown old bloody discharge. I don't really know what this is. Could it be signs of miscarriage? Is the bleeding from the IUD removal? If any medical professionals use this any info would be appreciated. Thanks!
