Just diagnosed after leep procedure

After multiple doctors told me that there was too small of a chance, I was too young, it takes YEARS to progress, I just got the call that I have cervical cancer. I am 30 years old and went to the ob/gyn after a trip to the ER for a three week long period and extreme cramping/pain a couple of months ago. I was told that the cells were precancerous after my colposcopy, and that it was caught early.

My ob told me that now I am looking at a hysterectomy even though they told me it was a small area and it's unlikely that it has spread. I have an appointment with an oncologist in a week. I don't know what to expect since I have been dragged along for six months of doctors telling me that I am fine and just depressed. I am beyond upset and don't know what to expect now.
