How does Mirena look and feel?

Mirena is a small, flexible, plastic, T-shaped IUD (intrauterine device)

Mirena® placement in woman's body

Mirena is placed in the
uterus by a healthcare
provider during an
office visit and takes only
a few minutes

Everyone is different, and some women may experience discomfort or spotting during and after placement. These symptoms should go away shortly. If they don’t, contact your healthcare provider, as Mirena may not have been properly placed. Within 4 to 6 weeks, you should return for a follow-up visit to make sure that everything is okay.

Mirena is placed in the uterus, not the vagina, so neither you nor your partner should be able to feel it during sex. If you or your partner do feel pain, talk to your healthcare provider

If you ever have trouble finding the threads or feel more than just the threads, call your healthcare provider right away. And in the meantime, use a non-hormonal form of birth control as a backup.
