C.N.
I had it seven years ago to stop periods from hell - cycling every two weeks, cramps so bad I doubled over and vomited, flooding like the Nile in springtime. The only thing I regret about it is that I didn't know it existed sooner.
I had no complications whatsoever, other than very mild cramping for a couple of days after. Since then, no periods, not even light discharge, no PMS, no chance of getting pregnant - win, win, win. And now I can wear my fancy undies without worrying about them getting bloodstained.
