Mirena and time 3

I'm 22 and have had my Mirena since April of 2006. At first I thought it was the best thing ever to have because I didn't have to worry about taking the pill on time, the patch that never stayed or having a shot that i don't like. My periods stopped completely within a month and I haven't had any since. I have recently felt like i am pregnant again due to the fluttering feelings in my stomach the tenderness of my breasts and the sensitive smell. My stomach cramps during certain positions of sex. Within in the last year i have noticed that i'm losing hair, my moods vary from day to day. I feel a constant pain in my back and fear that it has punctured through my uterus. I am planning on having it removed as soon as I can get a doctors appointment. I am ready to have the pain go away but the periods not to come back.
