iud concerns!!

i have been on the patch for a couple of years; i use the twirla patches. today my gyno said she wanted me off hormonal birth control due to migraines, she has concerns with it interacting negatively with other medications. she recommended a non-hormonal iud to me. i went ahead and made the appointment but i am extremely anxious.. i swore never to get an iud. she prescribed a couple of medications to take the day before to soften my cervix, and one other i’m not sure what it’s for. she also said i would be given pain medicine and she would do it with an ultrasound to be sure it is placed correctly and it would be done during the first day of my period. however i am beyond scared to have it done and wanted to come on here to collect anyone else’s thoughts regarding the process or advice or anything. today was my first pap smear.. this is completely uncharted territory for me. i am looking for any honest support or advice?
