I had the Mirena put in March of 2005 and I thought I loved it. UNTIL...... I started doing some research. I have had cysts on my ovaries since January of 2006 and questionable lumps in my breasts, very fatigue, very little sex drive,weight gain (typically weighing 108 I now weigh 122) and head aches every day. I always had an excuse until one day a light bulb went off it has to be the MIRENA. So I researched the side effects of MIRENA and behold I found everything I was experiencing listed about - buyer beware type thing. I had the MIRENA removed today. The cysts on my ovaries are about 2cm big and the lump is about 6cm big - I pray that having this thing out of me will resolve all of the problems I have had. I will keep you posted.
