hey sarak,
I am experiencing the same thing. My hands seem to swell when I am on my feet for long periods of time like walking around. ANd my feet and ankles are swollen all the time!
I have been worried about PE too, but at my last check up on Friday, BP was 110/70 and the one before that was 130/70. So I am not too worried about PE and nor is my doctor!
Some people just swell up, normal pregnancy thing unfortunately. And yes, I wait up in the mornings and my wrists are really sore and fingers and toes really tight.
Try and keep you feet above hip level whenever possible and make sure you drink lots and lots of water.
