"the trade off is a few hours of real pain for 3 years of not having to worry about birth control. i have never had children and i&#039;m 22 years old, so my cervix is really small according to my doctor. that&#039;s why the insertion, and the few hours after, hurt so very badly. however, since then i have felt no pain. i can&#039;t feel it ever. the best part is that my periods are incredibly light and only last one or two days! i am really glad i did this, and in three years i&#039;ll probably get another one."
