SJ, I never measured 'correctly' for any of my pgs. For DD2 I got to 36 by 40 wks. DD3 was even further behind - only to 35 (and she turned out to be my longest babe at 50 cm). My m/ws know I carry small. Are you at all concerned? In my case, DD3 dropped low around 32-33 wks and engaged early. What were your other pgs like?
