abnormal uterine bleeding
"Wow.  Thank you for all your stories.  I thought I was alone on this insanity.  I'm 41  years old now, I was 39 years when I got the Mirena.  Suggested to me by they gyno. I was referred to by the hospital as I went in  with such agony and after a few months of bleeding, fed up.  Always had ovarian cysts, normal, they tell me. I bleed all the time, like, my time of the month is when I don't bleed, which if I am a lucky gal, 2, 3 days in a row!  Had to get a polyp removed from my uterus, because, again, that seems normal. Oh yeah, Mirena is so great, you might not even have a period.  I'm thinking this is too much to be true.  I could have no sex life before, you know bleeding all the time.  So, I'm over a year with Mirena and still bleeding more than ever."
