Scan showed all fine, baby GIRL measuring a bit smaller than my dates, so thinking 6 Jan is a realistic guess for birthing.

But I was a bit surprised at the extra risk aversion in the scanning - said they now do a routine internal to provide even more analysis of cervix. I politely declined, since the u/s indicated all fine there anyway. Placenta is on back wall, currently 2 cm from cervix, again, just fine for this stage. Sonographer said some obs like it to be 5 cm away at term - what the?! I told her I wasn't seeing an ob, but a private m/w and in any case, even when I had, he was after 2 cm away at term with DD1's pg. I second guess even that advice!

All of my low lying placenta research classified it as a problem either over, or verging on cervix and there is some support for concern at less than 2cm, but 5cm seems just ridiculous. The no of 'elective' c/s you'd be scheduling at that point would be much higher.
