So I was a few points off my 3hr due to most likely having low blood sugar.   It makes very much sense to me, since I almost pass out on a daily basis-yeah no fun.  I was told that since my body isn't used to that much sugar at all, it caused my numbers to be a tiny amount out of normal range.  I don't start testing till tomorrow am.  My baby is measuring a little smaller too, which I'm used to as both my older kids were around 6lbs.
