I had a colposcopy done when i was 21. I also had a cone biopsy done at the time. It did sting, but i was very uptight and nervous. I was between CIN2 and CIN3 so had to then have the cells removed. I didn't have laser, i had a curette to remove them under a general.

Now, i just have to have paps every 12 months and there hasn't been a problem since.

Good luck hun. It's a bit of a nerve-racking thing...I remember!
