Is it normal to feel discomfort when the doctor checks the cervix?

The last few times my fiancee and i went into the doctor for the routine prenatal check up he has been checking the cervix being that she is 37 weeks this week he is going to do it again but i was wondering if it is normal for my fiancee to feel discomfort when he does this. every time he does it then leaves the room she always says jeez he has big fingers. and when he does it i can see the discomfort on her face.
