Listen to your body, if you know that something is not normal, like all the symptoms you mentioned, don't think twice and make the decision of taking mirena out. If you read other stories here, a lot of your symptoms are mentioned here. I my self regret now for taking so long to find out why I was going trough some many symptoms. Now I'm almost 9 months post mirena after having it for almost 6 years, and still trying to get better each day. I hope this helps you a little and decide to get it out. Now I know that anything against nature is not good. Not having my period for 6 years was definitely not good and here I'm fighting all the side effects from this.
