"i had mirena placed in july of 09. it was very painful. i had cramping and bleeding for a month, which i was told was normal.  the bleeding eventually stopped and now i have what i guess you could call a period.  brownish discharge with clots. i&#039;ve been told it&#039;s old blood. i&#039;ve had cramping off and on and usually a dull pain on my right side. i recently started having a burning irritation at the opening of my vagina. i went to the doctor because i thought it was a urinary tract infection.  i was told it was yeast infection. i took a 3 days of diflucan. was treated again for 5 days. was told everything is fine now. still having burning. i think it&#039;s the mirena."
