Girl Yes!! it is normal to be nervous. I was nervous all the way up into the O.R. I began to shake. Dr. P asked me if something was wrong or if I was just anxious and I said just anxious and then I woke up and it was over. lol. & question number two the office gave great advice to buy one of those airplane neck pillows to sit with. On the first day you’ll have to go back to your room with the dilator in and the neck pillow will help the commute back to the hotel. It helps because it raises you up off of the seat but has the hole for the dilator so it’s not uncomfortably pushing it further inside of you. I hope this helps. 🙂
