Second cone biopsy

I’m 28 years old and have had 6 colposcopys and 2 cone biopsy’s in the past 5 years. Iv had reoccurring cin 3 through out all of this. I just saw my second cone biopsy results (had it done on sept 11th) on my chart and the result was High-grade squamous intraepithelial lesion, present at 6-9 o'clock endocervical resection margin. Has anyone had this or know what it means?
