Now that you're using Mirena® intrauterine contraceptive's hassle-free protection, you can think about the moment, not your birth control method. And you can have peace of mind knowing that you're using a hassle-free birth control method that prevents pregnancy for up to 5 years (or less, if you choose).1
Since Mirena® works entirely on its own, now that it’s in place there's nothing you have to do2. Unlike other methods, it doesn't rely on your using it regularly and properly to be effective.

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.
