Hun, I think if you feel fine and don't have any other symptoms, don't bother, or do the urine test like Traveller suggests (didn't even know that was an option!). I have done it each time, but only because I had the opportunity to be there on my own if I had to drag the kids along too, then I would likely opt out too!! If your previous tests in previous pg have been fine, I wouldn't worry. Your babies are big because your DH is so tall. DS was 4.2kg and noone ever suggested it was because of GD to me, people always blamed that on DH! And he's not as tall as your DH is either I don't think!
