Hello, I have had the Paraguard IUD for 4 years, and I am 3 weeks late for my period. I have 2 children and miscarried twice. I haven t taken a pregnancy test and have had zero signs and symptoms of pregnancy. I do not smoke , and I have never had intercourse with anyone other than my husband. Three days ago, I experienced dark brownish/ black menses and have had discomfort in the outer vaginal area. Can you help me diagnose?
