Hi, I had a surgical abortion 5.5 weeks ago and had a copper iud inserted. I am still experiencing some spotting, but three days ago I noticed that I had very thick, clear/ cloudy mucus tinted with blood. This went on for two days and then there was light pink spotting again. I took a pregnancy test, since the mucus resembled mucus plug, and it came back faintly positive. I repeated another test the following morning and it was again positive. Am I pregnant again or is this a combination of remaining HCG in my body and the IUD causing the mucus?
