"i have read a lot of negative comments on the iud insertion so i just wanted to share my positive experience. before hand i took two vicodin about 1.5 hours before the appointment. the actual insertion only took about a minute. and, yes it was painful but it was over so quickly that it wasn&#039;t that bad at all. i would do it again. the night i got it in, i had crams that felt like bad period cramps but nothing some advil couldn&#039;t help. everyone is different but it was not as bad as i was expecting."
