First colposcopy

my follow up pap smear showed low grade changes to my cells since last year, my dr sent me to get a colposcopy in a few days just to be safe.

 

I understand cervical cancer takes many years to develop and there are many options for me to treat it early on if I had to, but I’m terribly afraid of the procedure and have had bad experiences with speculums. I know it’s necessary I do this but is there any way I could have some sort of gas or pain killers before the colposcopy? 

Im afraid I’ll be too tense and anxious and it’ll just cause me more discomfort and make it harder for my dr to examine me.
