2. Double check. Being able to feel your IUD strings is totally normal (here’s a handy how-to). But if you can feel the hard plastic protruding from your cervix, the IUD isn’t where it’s supposed to be. For some people, it may be less noticeable if the IUD has expelled. It’s definitely a good idea to make an appointment with your provider if you have any of the following symptoms: severe pain and cramping; heavy or abnormal bleeding; abnormal discharge; and/or fever. (This may also be a sign of infection.) Some discomfort in the first few days after insertion is normal, but if the pain intensifies or persists, it may be time to see your provider.
