22 weeks check up

Anyone know what happens at 22 week check up? I have a doctors appt. tomorrow and have a few hemorrhoids. I will be so embarrassed if they have to do a vaginal check. I had a papsmear at 12 weeks the doctor didn’t warn me about. Just want to be prepared this time. I already had my anatomy scan at 18 weeks. Not sure why I had a pap either. Doctor didn’t explain why. TIA.
