I just had my iud put in last month. And yes i have never smelled so bad in my life. Im afraid to bend over or sit down beside someone because i super stink! But it makes sense...the mirena iud is supposed to keep the lining of your cervix very thin. So i think its the lining shedding constantly that makes the smell. I am certainly going to try some feminine products to try and reduce the smell...any suggestions? Of coarse everyones body chemistry is different.
