I just had Mirena inserted sept 12 ( 2 weeks ago)-had major cramping and discomfort-but basically went well. Since then i've had the "normal" cramping, pain, and nonstop bleeding. I've had major mood swings and irritability (not the norm for me!)-- and more pressing heart palpitations, arm numbness, insomnia (although im extremely tired--2 month old come on!) The scariest thing is yesterday morning i was lying in bed and my head began spinning--and i was extremely nauseous--and vomiting all day-im still extremely dizzy and can barely get out of bed still!!!!! All this within such a short amount of time....I called my ob/gyn--and am waiting for the callback..i even took a pregnancy test bc I felt as awful as i did when first pregnant! Man im glad my hubby found this site (he was searching to see if mirena causes such symptoms) at least i see other women are experiencing such crazy and similar symptoms as well...ive got to get this thing out-and im not takin no for an answer! -i feel soooo awful ...this dizziness is crazy....comments anyone??
