Lost strings are another problem, making removal difficult. Full-term pregnancies have been reported with an IUD in place, but if you do get pregnant while you have an IUD, there's a 30 percent chance you'll miscarry. If a miscarriage does occur, there's an increased risk of infection. Some of these infections can be fatal. Punctures in the uterus or cervix are another drawback to IUDs and can lead to pelvic infections.
Insertion can be very painful.
Bring along a friend or spouse. Don't walk home or drive home yourself. Take an Advil, Nuprin, or Anaprox before you have it done. It will tell you about the risks and warning signs for removal. Make sure your doctor shows you how to find the string.
