I have had Mirena since Oct. 2007 and ever since have had frequent yeast and bacterial infections. Also my stomach has these gas pain attacks where I feel like I am going to die, it hurts all the way up my back and feels like a huge ball of air is trapped in my stomach. I also have pain all the way up both sides of my chest as this happens. I never made a connection to the mirena just thought I had some weird problem. My strings also disappeared and I had to pay nearly 300 just to make sure the thing was still in there. I was told if he can't get them he will need to do a surgical procedure to remove it- great and I got this to avoid surgery of have tubes tied! I have also been moody, depressed, no sex drive and when I had strings they poked my husband and made sex difficult. I spot constantly and I too have ruined all my panties from this brown old blood that comes out unexpectedly. My husband insists that I have it removed and after seeing that I am not alone in what I am experiencing I am going to see my doctor as soon as he opens. I have been up most the night with one of those gas pain attacks and I am miserable! I recently have been feeling as though something is kicking me in my intestine or stomach area too and I too look pregnant all the time and in fact the 20lbs that I need to loose is all belly! Thanks everyone for all the great advice wish I would have seen this before!
