Abnormal pap

So when I was pregnant my doctor told me I had an abnormal Pap smear I had a miscarriage so now my doctor wants me to have a colposcopy to check for hpv/cancer I’m scared and nervous and the appointment is coming up next week which suck. Especially since I’m ovulating next week and I can’t have sex a week after my procedure. My question ladies has anyone had this procedure done and what can I expect from it?
