"my 1st paraguard had to be removed within a few months because of a painful endometriotic infection. i had a 2nd iud put in 2 years later, at which point i started getting   low-grade squamous intraepithelial lesion (lsil)  pap results, which have continued for the 10 years that  i have had the device: i think the chronic inflammation caused by the iud prevents my body from healing this. in the last 3 years breast cysts began proliferating, some infected, which baffle the doctors because they associate them with taking hormones: copper toxicity can cause hormonal imbalance. i have had regular, off-colored discharge &amp; frequent spotting. i have had an extra period (2 in 1 month) 3 times a year, &amp; my periods last for 7 days (once 4 weeks). my migraines have intensified, &amp; i often have cramping."
