It's been cold in Canberra but this week I am finding that by mid afternoon my feet and hands are like ice-blocks and I just can't stay warm. DH is running around in a t-shirt at night and I'm on the couch with three layers on...

I've read you can feel the cold more when you're pg but this is ridiculous. Going for a 15 min walk helps slightly (as long as I really rug up) but I have to work at my desk most of the day and can't really afford to keep nicking out for 15 minute walks. Besides I'm pretty knackered after one.

Any tips?
