Abnormal Pap/HPV?

So I had my first OB appt at 8 weeks about 2 weeks ago where I got tested for everything and also had a Pap smear done. Well they called me a few days ago to tell me it came back abnormal for HPV so they want to do a more thorough exam at my next appt on the 18th. It's called a colposcopy? I admit I feel rather confused and worried and wondering if anyone has gotten these results and what happened thereafter?
