"i&#039;m 28, never been pregnant. i have had the mirena for 3 months now. it wasn&#039;t the best of experiences at first. insertion was painful but the pain was very brief. i had some bad cramping for a week or so and non-stop bleeding for nearly a full month. however, slowly but surely, it got better. i finally stopped bleeding and only occasionally do i have some spotting - nothing a pantyliner can&#039;t handle. so far, i&#039;ve had two real periods; the last one was a lighter flow than i&#039;ve *ever* had though it did last more days. the pain during menstruation is a lot less intense then pre-iud. sex is worry-free now that i know for sure that i run a very low risk of getting pregnant. i&#039;m very happy with it!"
