Did you know that at 20 weeks...the measurement from your pubic bone to the top of your uterus (belly button) should measure 20cm?
That's what doc told me! Said everything is right on track. And I got to "hear" the heartbeat for the first time
(since my placenta is in front...it took a good minute for her to find the heartbeat, ahhh, she told me to wipe the panicked look off my face)
