I went into my gynecologist last week because my IUD had slipped and was causing extreme abdominal pain and constipation. They removed the IUD which was lodged in my cervix, and determined I was miscarrying. I did not know I was pregnant, I have been spotting somewhat, I have a headache on the left side of my head (that ibuprofen is not helping), heartburn and I have been having to drink milk of magnesia because I am still constipated with pain in my rectum and my right shoulder when trying to go.
