Mirena
"After my second child I decided to use the Mirena. I have been using the Mirena since 2005! The insertion was not painful. A little cramping about a day after but that was it. I would occasionally get spotting a few weeks after insertion but nothing heavy. Haven't had a cycle in years. I had the Mirena replaced in 2010 with no problems. The Mirena is a great choice for birth control. "
