PZ: Your weight and height is similar to mine pre pregnancy for DD and also this time. No GD both times - even though carrying twins is classified as 'high risk' - my results this time were a little on the high side of normal (7.3) but still fine.

Ultimately it is your decision but I decided to have to have it done both times as it is not a major test, just a glucose drink and then a BT 1 hour later, as I wanted to make sure not just my health but the health of the baby/babies was managed as well.
