I had my Mirena inserted in January, 2 months later i stopped bleeding, i have spent several days waking up with the same type of nausea i had when i was Pregnanat. 10 days later i experienced excruciating pain in my left side of my abdoment that is so intense it makes me double up, it feels as if something goes pop before the pain relapses this happens every 3 weeks, i have a dark discharge every 3 weeks that lasts for 8-10 days, i have lost my sex drive altogether, my tollerance level is less and frustration comes easy. Over the last week i have experienced contraction like pains that last about 20 minutes. I went to my local gp's to get it checked 8 weeks after insertion, i was told my Gp isn't qualified to do this i would need to go to the sexual health clinic and see the nurse there....
