Yokyil as others have said, rest and more rest! A cold flannel helps for me as well, although mostly as a slightly nicer sensation than the headache itself rather than any actual relief from the pain.
brickie while it must be an absolutely horrible, stressful time, I'm glad they're seeing you again and not just leaving you to wait it out. Lots of
and fingers crossed for you.
tiny sounds like you're dealing with it well! My DH and I have periods like that when we're both sniping at each other and it just makes things worse. If you can keep you cool and try to stay calm, it'll help defuse situations before they develop. And glad to hear your OH appreciates the effort you're making 
tonic hope you're still in bed and being brought lots of cuppas and biscuits! Glad you've had reassurance.
valancy - so sweet! Our 'telling people gradually' is being derailed somewhat by DH waving our scan picture around willy nilly, it's cute - we've also got it on the fridge, mostly so I can keep reminding myself it's actually real...
Back/hip/top of leg/whatever pain has eased a bit today, still achey and twinging a bit when I walk but nothing bad enough to stop me getting around, hooray. My sister had a horrible pregnancy with SPD that had her pretty much housebound from 5/6 months onwards and I'm really hoping to stay active!
