What Is The Side Effect Of Novasure Procedure?

Hi. I am a 43 yr. old woman who is done with child bearing. I have been thinking about the Novasure procedure to lessen my mensteral flow. Compared to some women mine is a walk in the park but mine has started to interfere with my life. I have heard some horror stories from women who have had this procedure but a lot of them are from women who had the procedure 5+ years ago. With new technology and research I was wondering about the side effects of this procedure.
