Get your iud out asap. Mine perforated my uterus shortly after insertion and after 3years of tests was in my abdominal cavity under my liver!! No one listened to me about my pain. I think i was being too nice. You should not wait a second to have it removed call your m.d or the office manager and tell them it must be done asap./ They are already at fault and are putting you off!!! Take care of your self because they are taking care of themselves instead of you. You will be fine but stand up for yourself and make them do their job or fire them and get a new md.
good luck!!!
