After more than a year on the nuvaring (which worked wonderfully) I decided to go a more permanent route with the mirena iud. I had it put in three months ago, and I can't believe the side effects that have come with it. Sudden weight gain, horrible breakouts, zero sex drive, and SEVERE mood swings. I feel like I'm on the verge of a breakdown everyday. I would trade having a period for this any day. Needless to say, my iud will be coming out very soon. I don't know how some of you can deal with this for such a long time.
