"i am a 40 year old, who has never given birth and i had the mirena placed 3 months ago, to try to alleviate very heavy menstrual bleeding.  the insertion was quite painful, but only lasted a few hours.  i did bleed for about a week afterwards.  i&#039;ve had my period every month since, but i do not need to use tampons.  am hoping that within the next 2-3 months, it will get even lighter.  i still have some cramping, but nothing compared to before the insertion.  i have read lots of comments with bad experiences, but i guess this is not for everyone."
