I am so happy to find this site and to know i am not alone in what i am feeling since having Mirena put in! I have only had the IUD for the past 8 days and that is 8 days too much. I have been feeling worse each day , My whole body is aching , I am so tired i cant seem to do anything but sleep . I cant stay motivated for any time, I am sweating and shaking with Heart pounding like it's coming out of my chest! My legs are hurting like i ran a marathon every time i get up i feel so Dizzy and Faint! My God the list is never ending not to mention my mood swings, At this moment i am waiting to hear from my Gyne office i want this thing out of me Tomm ! I cannot believe that i feel so horrible . I would rather deal with my heavy , heavy Periods and cramping then deal with the side effects to Mirena ! I knew it sounded to good to be true and why my sister the RN was really not saying much when i told her i was going to have it inserted only adding that well i guess your Doctor knows whats best! I will keep you updated .
