Is it Possible to Still Get Pregnant While Having an IUD In Place?

The possibility of pregnancy exists with any contraceptive.

An IUD, or intrauterine device, is placed in the uterus to prevent pregnancy and can work for up to 10 years. Although the IUD is an effective birth control method, it is still possible to get pregnant while having an IUD in place.

Effectiveness

The two common types of IUD in the United States, ParaGard and Mirena, are about 99.4 percent effective at preventing pregnancy. While this means that less than one out of every 100 women will become pregnant while using an IUD, there is still a slight risk.

Medications

The IUD is not a hormonal contraceptive, so it is not likely that antibiotics will reduce its effectiveness. But check with your doctor before taking other medicine to make sure you will not need a backup contraceptive.

Expulsion

While uncommon, an IUD can become dislodged from the uterus without you realizing it. If the IUD comes out of place, you are at risk of becoming pregnant. Some doctors recommend that you make sure the IUD is still in place by checking monthly to see if you can feel the IUD strings in your cervix. If the strings are missing, call your doctor and use a backup method.

Ectopic Pregnancy

Women who become pregnant with an IUD in place run a higher risk of having an ectopic pregnancy, or a pregnancy that develops outside the uterus, often in the fallopian tube. If you experience abdominal pain, heavy bleeding, shoulder pain or pain during intercourse, contact a doctor, as these may be signs of ectopic pregnancy.

Pregnancy Risks

Becoming pregnant with an IUD in place can put you at higher risk of having a miscarriage or premature delivery. You should have your IUD removed if you become pregnant while using it.
