Levonorgestrel
"Went on Mirena as it was one of my only options for birth control due to hormone issues and aura migraines. It hurt pretty bad having it put in. I suggest 800 mg of ibuprofen a half an hour to an hour before insertion. I have never had a child. Right after insertion I felt great, no pain for a few hours, then the cramps began. Nonstop terrible cramps with a little bleeding, for 3 full days. I finally called the Dr and she wrote me a script for Vicodin so I could go to work. No sleep for those 3 days due to terrible pain. The cramps finally subsided but then the stabbing pain started. Terrible stabbing pain in my abdomen. I think my body was rejecting it. I had it removed. Feel much better."
