same experience. sa 1st pregnancy ko, there was no OGTT. but on my 2nd pregnancy, marami na pinapatest. one of which is OGTT. i understand since malaki ang gap ng 2 kids ko, may new protocols or new tests to check pregnant women for intervention to avoid risk/complication. sa OGTT, aside from fasting, sugar is checked after taking glucose or sugar kung tataas ng sobra.
