Refuse Pap smear while pregnant

Bee
I don't think it's wise to get a Pap smear while pregnant. I'm up to date and happy to do it after giving birth. I've had too many friends miscarry a day after. I had to find a midwife so she would let me decline it because my OB said she wouldn't keep me as a patient if I decline it. Did anyone else decline or do you have experience relating to this situation?
