Hello and welcome to Pearl.com. I amCustomer and I look forward to helping you with your problem today. A urine infection will not infect the uterus or IUD area. Also, an infection in the IUD could not be transferred during sex to the urine. They are separate areas (although fairly close to each other), and an infection in one never goes to the other, as far as I know. I agree that you'll know more when you talk to your doctor.
Thank you for your payment.
