Hi, I'm 24 weeks and have an appointment for the GTT at 9am tomorrow. I thought it was a 12 hour fast period before the test and finished dinner about 8.30, but I just checked my letter and it said not to eat anything after 8pm, not 9pm. I'm wondering if the letter's just over cautious and assuming people will push the boundary a bit past whatever time they state, so says 8pm instead of 9pm - but have I got it wrong and it's actually a 13 hour tasting period before the test? Anyone know?
