What should I watch for?

Visit your doctor or health care professional for regular check ups. See your doctor if you or your partner has sexual contact with others, becomes HIV positive, or gets a sexual transmitted disease.

This product does not protect you against HIV infection (AIDS) or other sexually transmitted diseases.

You can check the placement of the IUD yourself by reaching up to the top of your vagina with clean fingers to feel the threads. Do not pull on the threads. It is a good habit to check placement after each menstrual period. Call your doctor right away if you feel more of the IUD than just the threads or if you cannot feel the threads at all.

The IUD may come out by itself. You may become pregnant if the device comes out. If you notice that the IUD has come out use a backup birth control method like condoms and call your health care provider.

Using tampons will not change the position of the IUD and are okay to use during your period.

This IUD can be safely scanned with magnetic resonance imaging (MRI) only under specific conditions. Before you have an MRI, tell your healthcare provider that you have an IUD in place, and which type of IUD you have in place.
