Punch Biopsy With Low Grade Changes?

Today I had my Colposcopy following an abnormal smear. 

I was told my abnormalities were low grade. 

During the colposcopy he saw 2 white areas which he took a punch biopsy from. I wish I would have asked more questions but I got myself in such a state and couldn’t stop shaking. 

I’m wondering why he took a biopsy for low grade changes as I thought it would just be a follow up in 6 months? 

Thank you for reading x 

I also had mine but on 18th march I have Borderline changes and HPV positive I also had a punch biopsy because of 2 areas top and bottom. It was from my first smear I'm abit late! I'm 27 so I'm new to all this I didn't ask questions either I wish I did now as I'm going to be worrying alot! please update if you get your results before me lol. Xx 

Hi girls I am in the same boat. Had colposcopy today. Was told CIN1 before & during but she took biopsy anyway “for reassurance” - has scared me as really wasn’t expecting it for low grade..
