My OB at the hospital suggested I wait until after PG. I was due a pap smear when I saw him for my 12 week check and he said he could do it and wouldn't hesitate if i wanted him too, but also that it was better for my uterus to wait until 6 weeks after the baby is born.... so I decided to wait. My GP also said she would wait until afterwards just to be safe, also that she wouldn't suggest doing it in the first trimester anyway....

I hope that helps!
