"i had inserted mirena almost 4 months ago. i experienced heavy bleeding about 2 weeks after i got it and everyday after that up until the 2nd month. it started off heavy and gradually lightened up but the heavy bleeding lasted almost a month and it was everyday. the doctor that inserted it said this was normal and the further from insertion date i got it would get better. i&#039;ve found this to be true. i am happy with mirena."
