Checking your strings regularly can help assure you that the Mirena is still in place. Most healthcare providers recommend checking the strings once a month, between periods. Some may suggest checking as often as every 3 days during the first 3 months after insertion, since this is the period of time when the Mirena is most likely to slip out. Wash your hands with warm, soapy water, and rinse thoroughly. Then dry off with a clean towel. Squatting or sitting will make it easier for you to reach your cervix. Get into a position that feels comfortable for you. Use your middle or index finger. Your cervix should feel firm and slightly rubbery, like the tip of your nose.  If you have a hard time getting your finger into your vagina, try coating it with a bit of water-based personal lubricant first. You may wish to shorten or file your nails first to prevent scratching or irritating your vagina or cervix. Once you have found your cervix, feel around for the IUD strings. The strings should be protruding slightly from your cervix, typically by around 1-2 inches (2.5-5 cm). Do not pull on the strings! If you notice any of the following signs that the Mirena has started to move out of place, check with your healthcare provider:  The strings feel much longer or shorter than you expect. You cannot feel the strings at all. You can feel the plastic end of the Mirena device.
