I have been the same and in the same situation....

I sit infront of a computer all day, BUt my ankes have been swelling up so bad they look sprained and it hurts to walk.....

My BP was hovering around 130/70 then i went 110/70 then last visist went to 130/80, my fingers are a bit puffy and so is my face NOT severly tho but noticable.....

i was concerned too but am waiting until my next app (next wed) but i have now cut down my hours to 6 a day instead of 8 and finishing for Mat leave end of next week.....

I am 35 weeks tomorrow.....

Good luck and lets hope we both dont end up with Pre-eclampsia......
