The : The chances of becoming pregnant with Mirena (levonorgestrel) iud implanted are very low. The Mirena (levonorgestrel) iud is over 99% effective for birth control. The Mirena (levonorgestrel) iud releases the hormone progesterone, which can cause abnormal menstral cycles and spotting, but also guards against allowing an egg to implant in the uterus. It is about time that you have a physical examination by your doctor, since it has been a year since your iud was placed. It is prudent to have your iud checked to ensure it is still placed correctly. If it is still in place, the possibility of pregnancy is very low.

Low chance : Chance of pregnancy is less than 1 out of 100 each year with Mirena (levonorgestrel) iud. Remember that periods are lighter and can be irregular with that iud. That being said, if you think you might be pregnant and especially if you have pregnancy symptoms check a pregnancy test.
