I'm doing my GTT on January 13th. Doesn't that seem early? I'll be 24 weeks then. My OB is already asking me to do 2 week apointments too. (I wouldn't this last time, because of obligations, but I guess I will after this.) I just can't believe I'm that far along! I'm quite sure that my previous OB and midwife did not monitor me so frequently so soon. It seems like I didn't go in biweekly until the last month and weekly only after 40 weeks.
As for the GTT debate. I just do it because I fight so much other stuff, and have a history of very large babies. Knock wood, I've never failed the GTT.
