Thanks LC - that's most likely the test (though the words POAS were used when I was told about it, but I think this may be what she meant).

What you say makes sense too and is food for thought - if I did get GD with this pregnancy (I did with DS1, not DS2) then I'd prefer it be picked up sooner rather than later. Still, maybe the dipstick test builds a picture up if done with some regularity, rather than a once-off GTT. Hmmm ...
