Question: how common is it to get pregnant on kyleena?
Answer: There are two main types: copper IUDs (ParaGard) and hormonal IUDs (Kyleena, Liletta, Mirena, Skyla). Both types of IUD are more than 99 percent effective at preventing pregnancy, according to Planned Parenthood. Over the course of a year, fewer than 1 out of 100 women with an IUD will get pregnant.
