Referred back to colposcopy

Hi, was wondering if anyone could put my mind at ease? In December 2019 I had to have a biopsy after my screening showed abnormal cells and I was HPV positive. I was diagnosed with cin 2 and had a LLETZ procedure performed in January. In July I had my 6 month check up and the results came back as HPV positive but no abnormal cells detected. I've been referred back to colposcopy. I'm feeling anxious as I don't really understand why or what they're going to be looking for when I go back. I'm worried about being hpv positive as I know it carries a higher risk of developing cervical cancer. Has anyone else been in this position and have any information they could share? Thanks x
