Well first i want to tell you that MIRENA
is a intrauerine sydtem,which is removed just by pooling the threads from the vagina. It need not not be removed by perforating the uterus
.Well perforation of the uterus by any means seals itself by body's healing mechanism. It doesn't cause strong vaginal odour.
Well I just want to know whether your cervix
is normal or not, or any tear in the there in the cervix as a result of prior childbirth ,which can cause persistent discharge, and can be corrected.You can take an empirical course of broad spectrum antibiotics like azithromycin
even if no infection is detected. I think you might be having a psychological factor as well pertaining to MIRENA use.You can try with a short duration treatment with preprobiotics as well, if everything comes out to be normal.
good luck and dont worry.
