"i had my mirena put in a little over 3 months ago. i&#039;m 24 years old and have no children nor have i ever been pregnant. the procedure to put in the iud was very painful for me and although it only took 10 minutes it felt like forever. that being said i feel like it would have been better if my doc would have told me that it would hurt worse than just &quot;mild cramping&quot; and i would have taken a better painkiller other than the 200mg of advil she suggested. that first night was almost unbearable and the next two weeks were not much better. i spot bled for about a week until i got my period which lasted for 13 days. after that however, the cramps stopped and so did my period. i think it was worth the pain at first for the convenience of no pill."
