When do cervical checks start??

Angela

I’m currently 26+1 with my first baby and my next appointment is the glucose test, but I was wondering if any of y’all could tell me when cervical checks start? It’s silly but I’m kind of nervous for them and I want to be mentally prepared. So far all of my appointments have been just check ups with the heart rate Doppler and asking questions etc. When did you start to have physical exams? Thanks in advance!
