Cervix Check Pain

I don't understand how I can have one doctor check my cervix and it not bother me one bit. Then the next week a different Doctor checks me and it hurts so bad I feel like I'm going to pass out and ends up leaving the office in tears. I'm freaking out! If it hurts that bad just to have my cervix checked how am I supposed to push out a baby?! Feeling a little down this morning.
