Mirena
"I have had my Mirena for over 2 years now.  It was inserted due to heavy bleeding and cramping, which comes with age, as I was told.  I am 47 and have three teenage children.  Overall, I love it.  I have thinner hair, but that happened before the IUD was inserted.  Ladies, this is a fact of life for many of us. Oh, and the weight gain too. Here is my concern:  My periods have been extremely light to non-existent, lasting about 3 days.  Recently, I had a two week period with a week off, then it started up again and I have been going for 4 days now.  "
