I am having outpatient surgery next week to replace my Mirena, after having it fitted 6 weeks ago and now I have a fever? I orginally got the Mirena 6 weeks ago. After 2 weeks I couldn t find the strings. I went in for an exam and the doctor couldn t find it either so I went in for an ultrasound . It showed that it had moved and needs replaced. Leaving it where it is will possibly cause my bleeding and cramping infefinitely. Over the past week, I have noticed feeling nauseus, cramps different than normal, foul smelling bloody discharge, severe vomiting for an entire afternoon and now I have a low grade fever of about 100 degrees F. Should I call the doctor or just wait until my surgery next week? Thank you.
