I was the 1% who somehow got PID from IUD insertion even though I'd been tested a week before and hadn't had -any- sex for weeks before that.
Pelvic inflammatory disease (PID) concerns have been linked to the IUD for years. But it is now known that the IUD itself does not cause PID. Instead, if you have a genital infection when an IUD is inserted, the infection can be carried into your uterus and fallopian tubes. If you are at risk for a sexually transmitted disease (STD), your doctor will test you and treat you if necessary, before you get an IUD.
Technically they can say the IUD does not cause infection because the actual device does not, it's your body being opened up to put it in that exposes you to whatever "elements" are out there. I didn't touch anything suspect from the time it went in to the time it was taken out (can't do much when you're hunched over for 5 days). They took it out and diagnosed me with PID. So what caused it, then?
