Colpscopy appointment

Hi I'm new here, I'm very worried as I have had a appointment through for a colpscopy, I had a pap test in feb and didnt recieve my results just a letter from my dr saying she wants to discuss my recent results and a appointment for colpscopy at the hospital this Tuesday coming 10th march 2020 I have been treated for a abnormal cell changes a couple of years ago and regret to say I never kept up with the cervical screenings at the drs I so wish I did. So my question is could this be something serious as I havent received the results and the letter from the drs is concerning me, it's the weekend so there is nothing I can do to put my mind at ease. Thankyou
