I had my mirena inserted in November of 2008 and since that time I have had irregular periods. And by irregular I mean, lighter periods but for extreme lengths of time. Most of mine last from 7 to 14 days at a time and are only gone for about 20 to 25 days in between (if I am lucky). Up until about 2 months ago, that was the only real side effect I noticed. But then I got hit with intense migraines (the current one has lasted over a month now with little relief) a major breakout of acne both on my face & back....something I have never had before, major mood swings (violent at times) I have lost my temper with everyone and for no reason at all and then 10 mins later I am crying and (big deal for me) a semi-big weight gain (147 in November and 182 now) with no change in diet! So needless to say that even though the convenience of not having to take a pill daily and the cost I am saving is amazing........I can't say that it is worth my sanity or the lives I am affecting with my attitude! I think I will schedule to have it removed next week! Can anyone tell me if it hurts to have it removed?? I think it hurt putting it in so I am nervous to get it out!
