Abnormal pap smear

I’m 21 and just got my first Pap smear. My doctor called about 4-5 days later saying that they found abnormal cells and that I need to come back so they can do a colposcopy. I got the hpv vaccine when I was younger so I don’t understand how this could have happened. My appointment isn’t until another 2 weeks and I’m deathly afraid of why my cells may be abnormal. I can’t get it off my mind and continually cry when I think about it. I’ve only slept with 2 people. Has anyone been through this? I’m scared it could be something bad. I feel disgusting in my body and hardly want my boyfriend to touch me anymore for fear he could get something from me that I never knew was wrong. Any advice?
