Common concerns from people using IUD

Final section. Do you want to return to method navigation?
  • The discomfort that some experience during the insertion lasts no more than 20 min and this method is GREAT for many years, so it's worth it for sure! Also, get through those first 3-6 months as those can be sometimes difficult but afterwards its totally amazing. I had an EXCELLENT experience with NO irregular bleeding or cramping after 1 month.
  • Initial insertion is not the worst pain in the world, but it is a short, 30-second intense sensation that I would not seek out in the near future. For 3 months, following insertion, I had light bleeding (~ 1-2 pantyliners/day), which was not something my physician had mentioned was not just possible but also common.
