Once your body adjusts to Mirena® intrauterine contraceptive, you may find your periods may be:
After Mirena® is placed, you may experience heavier periods over the first 3 to 6 months because the lining of your uterus is shedding. This may also result in irregular periods such as “spotting” (a small amount of blood loss) or light bleeding outside of your monthly period. During this time, you may need sanitary protection, like you do during your period.
Remember, these menstrual changes are not harmful. The reason you may eventually have a shorter period, or one with little or no menstrual flow, is because of the thinning of your uterine lining. When Mirena® is removed, your uterine lining and menstrual cycle will return to the way they were before you used Mirena®.

IMPORTANT INFORMATION ABOUT MIRENA®:
Only you and your healthcare professional can decide if Mirena is right for you. Mirena does not protect against HIV or sexually transmitted diseases (STDs). Candidates for Mirena have had a child. Mirena is not appropriate for women who are or may be pregnant; or who may have a distorted uterine cavity; acute genital infections including pelvic inflammatory disease; cancer of the cervix, uterus, or breasts; unexplained vaginal bleeding; or acute liver disease or tumors (benign or malignant). In rare cases, perforation or embedment may occur. Mirena may become completely or partially dislodged. In the rare event you think you're pregnant, contact your healthcare professional without delay to be evaluated for ectopic pregnancy. Ovarian cysts may occur and typically disappear. Persistent cysts should be evaluated. Missing periods or irregular bleeding is common in the first few months, followed by shorter, lighter periods.
You are encouraged to report negative side effects of prescription drugs to the FDA.
