Cervix checks?

Are they suppose to be extremely painful? I was checked once at my doctors office cause they thought I was going into pre term labor and it didn't hurt at all it felt like a normal Pap smear and then lastnight I was at the hospital with Braxton hicks and they checked me and it hurt like a mother, I was in tears. She said I was closed but he was extremely low. Could that be why it hurt so bad? Or was she just doing it wrong?
