I just found out I failed my glucose test. I am so bummed. I was so careful not to eat/drink sugary things a few days before. A few friends said they failed the first test and then when they went back for the 3 hour they passed. I'm wondering if anything else besides actually having gestational diabetes could have made me fail. Did I do anything wrong? The nurse told me to drink the stuff as fast as I could so I drank it in exactly one minute. Then they took my blood an hour after I drank it. Did I do anything wrong? Is there anything I can do to better my chances of passing the 3 hour test?
