I have had my mirena since Dec 2004 its suppose too come out In Dec 15 2009 that would be my 5 years with it! I recently ended up in the ER with stomach pain, It felt like I was being stabbed to death from the inside out, they proceed to do a CAT scan on my pelvic and realized that a cyst had formed on my uterus and is connected onto the mirena!! I now have to go into surgery so that they can removed the cyst and mirena both! I'm scared that this has affected my chance of getting pregnant and becoming a mom! I'm getting married in June and this is just one thing that i never thought i would have to worry about!!! I just recommend that if anyone plans on getting the mirena that you do your research don't do it just cause your ob thought that it would be good for you!!!
