growths???

I am 40 yrs old.  I have had the Mirena for 5 years, then recently last August, I ah it replaced.  Everything seemed fine until the past two months.  I have had a swollen labia, anxiety, bleeding non stop and most annoying, growths appears on the inner labia and one right next the vagina.  I had a biopsy done last week (OUCH!!!!!!) and it was determined it was not cancerous and unspecified.  I am wondering if the IUD has anything to do with this, since I MAY be perimenopausal (that's what I am thinking anyway) and now the hormones in the IUD are counteracting with my own hormone levels???  Anyone have any suggestions or similar experiences?
