"i got mirena over a year ago, and for the first year it was great, but then i started to lose my sex drive. i didn&#039;t even suspect the mirena, then a few months ago i started having my period every other week, constant heartburn and nausea every morning, my breast became sore. i honestly thought i was pregnant but 5 tests said otherwise. i&#039;m going to my ob/gyn friday to get it removed and hopefully everything will improve."
