HSIL and hrHPV-

Hi! I am 23F and trying to come to terms with my recent Pap smear findings. Last year, my first pap came back as LSIL and hrHPV-. Due to my age and the high chances of regression, my provider thought it best to repeat the pap in 1 year. I recently repeated the pap and it came back HSIL and hrHPV- again. The HPV test used tests for all 14 strains currently considered to be high risk. I doubt that I could’ve gotten a false negative twice in a row. I am scheduled for a colposcopy after the new year, but am struggling to understand my situation and why I am having this progression despite seemingly being “negative” for the likely cause. Has anyone had similar findings? Additionally, I am worried that the colposcopy results may indicate the need for a LEEP procedure. My partner and I intend to start trying for children in the next couple of years, and I am significantly worried about the childbearing risks involved. Any guidance or support is greatly appreciated!!
