Thank you all for posting your stories about Mirena. I've had the Mirena IUD for almost 2 years. I have had a number of side effects from my Mirena that I did not realise until I read this blog and thought about when it started. The worst is the decreased libido, especially because I am a newly wed. I also have extreme migranes and cramping a couple of times a month. I have spotting and heavy bleeding at least twice a month for a week at a time. My sleeping has suffered, it takes me much longer to go to sleep and I wake up periodically through the night. I am getting a lot of acne. I'm 26 and have never had any children. I am going to get it removed soon but the benefit is that it is one of the least expensive contraceptive devices over the long term. There may not have been much testing during development about the level of hormones and the location of dispersal. I think the Mirena IUD needs redevelopment, it's a great idea but it looks like I'm not alone in the intense side effects.
