If you've decided to use an IUD, you'll need to find a qualified physician to insert and eventually to remove the device. He or she should have completed at least 5 supervised insertions before trying it independently.
You may have to go to the clinic a few days before your scheduled insertion to be checked for infections. In any case, you will need a routine physical exam and a Pap test to check for the signs of infection right before the insertion.
To reduce the pain and cramping that usually occurs during the first 12 to 24 hours after an IUD insertion, take aspirin or ibuprofen an hour before your appointment. You may also want to have someone go with you to the clinic and drive you home, in case you feel queasy, shaky, or weak.
