How should I use the levonorgestrel-releasing implant?

The levonorgestrel-releasing implant is a device shaped like a T that is inserted through the vagina and placed into the uterus. Pain or vaginal bleeding may occur during, and for up to 30 minutes after, the implant is inserted. The implant has a pair of strings attached. After each period, you will need to insert your fingers into your vagina to feel for the strings. This ensures that the levonorgestrel-releasing implant has not slipped out of place. Do not use these strings to try to remove the implant, as this must be done by a doctor. If you think the implant has slipped, call your doctor and use a backup method of birth control to prevent pregnancy. You should follow up with your doctor periodically, usually at four and 12 weeks after insertion of the implant, to make sure it is placed correctly. The levonorgestrel-releasing implant is effective for five years.
