I didn't realize you were an old pro at this baby thing! You know exactly what's going on! I apologize if I sounded preachy or anything. I just hate for first timers to pass on something that is non-invasive and can actually make a difference in the outcome of their pregnancy simply because they don't understand what the test is all about.
And I'm right with you on not wanting to do stuff I think is unnecessary. And I HATE the glucose intolerance tests to the point that I tended to put them off till past the optimum time and my doctor would get "cranky" with me. I AM glad that I did it though, since it turned out borderline once. That way I was able to correct my diet before there were any consequences.
Good luck and I must say, I'm a bit jealous. My fourth was my last, mostly for financial reasons. If things were different, my husband and I agree there's no telling how many we'd have!
