Hello there,
I'm five weeks pg with our first DC. Call me sad or what, but as I'm fascinated about how my body is going to change over the next eight months, I've started measuring my weight, hips, waist and boobs ever Saturday morning!
Today was the third set of measurements, and I'm surprised to see that over the last fornight I've lost 3cm on my waist and gained 3cm on my hips which wasn't what I expected. My weight has been pretty static. (OK, so I've gained just under 2lbs...) Boobs have only gained 1cm. 
I know my tape measure experiments won't be entirely accurate, but I'm intrigued to see if this pattern continues in the next few weeks before (presumably!) my waist finally starts to fill out. Anyone else noticed anything like this?
