Nervous need some words of wisdom

Hannah
Hello, 
My name is Hannah I am 20 years old and I'm getting married this Saturday. Anyways, yesterday I got a call from my doctor stating that my regular biopsy came back saying I have a stage 2 high grade cervical dysplasia. I am going in for a conization on December 16 to have the abnormal cells removed. I plan on having children but I want to wait a while and enjoy time with my soon to be husband. Just wondering if any women here have had the same thing done, and what their experiences were. I am quite nervous. Thank you
