I'm known as the Weeble in pregnancy. This can be tweaked according to circumstances; my unexpectedly stealthy movements in work = Ninja Weeble 
Very glad to say my physio appointment has turned up, just need to get it booked in; can learn some good stretches/yoga bits for the sciatica, which I'm sure will be good for my back in general and I'll keep up post-pregnancy.
As a first timer, I just devoured everything on Mumsnet, and that seemed to work- gives you an idea as to what the cause or solution to a certain situation may be, but it's a range of possibilities rather than a 'you must do this' approach. Two bits of advice from the feeding section that stayed with me were to get some of the areola in, not just the nipple, and "if in doubt, get it out"- if the baby's wailing, try feeding!
Had fun last night going out with friends/colleagues (we're all born in the same month oddly) just for pub grub and drinks (two halves and then softies for me, clearly). Meeting up with friends of DP tomorrow, and the woman in the couple is due within a couple of days of me! It'll be a bump-off...
