Mine was put in about a month and a half ago. I haven't stopped "spotting" since. I'm usually not one to complain of side effects and try to ignore them, but the moodiness is awful! My husband has been practically begging for me to get it removed. My skin has also broken out a lot more than normal. I think that healthcare professionals should really be more honest about the side effects. I'm getting it removed today. When I called my doctor's office and mentioned the emotional part, the nurse (which I love) kinda blew it off like it really wasn't caused by Mirena. I can't find another reason for it...
Didn't gain weight like a lot of other ladies, I actually lost a few pounds so I guess that's one good thing about it.
