Quoting Leash25:" ??? it's odd not to get one done at your 1st prenatal appt. they normally check r uterus to estimate ... [snip!] ... how far you are and if needed they do a pap smear. why would your dr wait until after your'e due to give you an exam???"
I think that's just the way we do it in NZ... unless you're leaking water or bleeding or something they pretty much leave you alone until you're in labor. I'd been contracting for two days, 5 mins apart for a min each, before my midwife did a cervical exam to check for dilation. They estimated how far I was with blood tests and a dating ultrasound, and at my first appt midwife gave me a swab to do a self-smear type thing. We tend to use midwives instead of doctors, I guess they're a lot less invasive.
