The hormonal IUD (intra-uterine device) is one of the best ways to prevent pregnancy, as it is more than 99% effective. You don’t need to worry about forgetting a pill. It is convenient and easily reversible. One of the benefits of the hormone containing IUD is it can improve menstrual cramps and make your period lighter. With that being said, you may have uterine cramps (ex. menstrual cramps) or a low backache for up to a few weeks after the IUD is inserted. There are more than one kind of IUD. With the levonorgestrel (hormonal) IUD you will likely have either much lighter and shorter, irregular periods (Mirena®, Skyla®, Kyleena® or Liletta™) or no periods at all (Mirena® or Liletta™). With the copper IUD (ParaGard), you may have increased menstrual bleeding and cramps; so this may not be the best choice for you. It’s important to know that IUDs do not prevent sexually transmitted infections (STIs). To lessen the chance of getting an a STI, be sure to use a condom every time you have sex. It’s a good idea to talk to your health care provider to find out which IUD is best for you. Be sure to get all of your questions answered and discuss your concerns with your provider before you decide to have the IUD inserted.
