I too had the same thing! I've had Mirena for the past 6 years and I never made the connection with the lichen sclerosis and the BV and yeast and everything else. Wow! I had a new one put in in January and it's driving me crazy!! I noticed a change in myself as well... no sex drive and my temper is volatile as hell. The side effects are getting too out of control and I have an appt with my gynecologist on Weds to get this thing out!! The only good part of this whole thing was I never got pregnant on it. I already have two kids and that's all I want pretty much so it worked well in that sense.
