The goal of this clinical trial is to perform a pilot study looking at the benefit of topical anesthetic application to the cervix by tampon prior to intra-uterine device insertion. The main question it aims to answer are: * Does patient tampon-applied local anesthetic prior to insertion of an intrauterine device (IUD) reduce procedural duration? * Does patient tampon-applied local anesthetic prior to insertion of an intrauterine device (IUD) reduce pain and improve patient perceptions of the procedure? Participants will place a tampon after dipping the tampon into the study-supplied medication (aqueous lidocaine or saline). Researchers will compare treatment and control groups to see if there is any difference in procedure time, difficulty or patient perceptions.
