"i really wish the mirena worked for me because i loved it... for a while. my body just plain didn&#039;t like it. i had it for a year and the last 4 months were horrible. i had about 12 yeast and bacteria infections that my doctor had no explanation for (i had never had them before). at a follow up ultrasound due to ovarian cysts they noticed my mirena had become displaced and decided to remove it. painful in one word- because it had become implanted in my cervix.  after it was removed the infections stopped miraculously. i really, really wish my body had accepted the mirena because i liked the worry-free birth control it offered. i will definitely try it again after i have kids and hopefully these problems wont happen again."
