I got my Mirena on the 1st of Sept. I had a copper IUD before with no side effects so i thought I should be fine. I have had cramping since insertion, a dull tenderness in my pelvis, almost a throbbing pain, spotting,nausea but not throwing up, and fatigue, and absolutely no sex drive... I feel gross. I'm have an ultrasound on Monday to see about the placement.. but after reading all of the other posts maybe i should just remove this thing before it gets worse.
