I am 27 weeks and I recently took my gestational diabetes test. I failed with a level of 150! I have to go back to take the 3 hour test to see if I have gestational diabetes! I don't understand why I would because my weight has always been normal, my blood pressure has been good, I've passed all the test so far, and my baby moves all the time... I'm scared I will have preterm labor if I have it.. Has this happened to anyone who was diagnosed with gestational diabetes ???!!
