Hi! My previous ob never had me take a glucose tolerance test until I was pretty far along in the pregnancy. (And my results were always normal.) Now that I've moved over to a new practice, I was surprised that I'm already expected to take one at just 7 weeks pg. They apparently automatically test overweight women and women with a past history of large babies (mine were 10 lb 10 oz and 9 lb 4 oz). How common is this?
