"i&#039;m on my second mirena. i had the first one put in after i had my youngest child. unfortunately, my insurance did not cover it so i had to pay for it out of pocket. other than the fact that the insertion is a bit uncomfortable (it&#039;s a sharp pinch and you may experience some light bleeding for a day or two) and the strings bothered my husband at first (i went back to the office and the ob-gyn trimmed them, and no problems since), i have had no problems at all. no pregnancy worries and virtually no periods at all (once a month i get the menstrual symptoms and maybe a little spotting for a day or two but not the heavy 6-8 day periods that i used to have to endure). i will be getting my third one in about a year."
