I would advise you against getting the mirena. However, if you do decide to get it, you will know about all of these possible side effects. I do encourage you to read through as many posts on this site as possible first. Some symptoms none of us associated with mirena, but then, after reading everyone's experiences, you start realizing just how many of your problems are related to mirena. If it doesn't cost you anything and if you are well aware of the possible side effects, but I would still advise against it.
