"i was so glad to see positive feedback on the mirena. i have only had it in for 2 weeks but really am fine with it. i do notice i have been a tad dizzy and sleeping a little less, i.e. waking up at 4am, but that could be stress of life as well. thank you all for posting something positive to read about this. i was really starting to worry i was going to have bad stuff start to happen. insertion was  fine, slight cramping for a couple of hours then slight cramping off and on for the next couple of days but nothing major at all. thanks again."
