What type of IUD do you have? I have a copper IUD (Paragard), but I know there's a hormonal type too, so they may differ. I've had the Paragard twice, once after my daughter was born, had it removed some 4-5 yrs. later to try to conceive a 2nd time (never did conceive that time), got the copper IUD again when I turned 40 and determined a pregnancy at my age is just too risky.

I never had any discharge with it except spotting upon insertion.

Best of luck with your doctor's appt.
