I have a hx of gestational diabetes. i'm 4 wks pregnant now and want to start off right. which artificial sweeteners are safe during pregnancy?

None: If you have had gestational Diabetes in he past most artificial sweeteners that contain aspartane will do you no favors in this pregnancy. Consider modifying that amount of sugar in your diet and possibly substitute honey which is a simple more digestible sugar. Talk to you OB MD about this issue when you make an appointment and congratulations on thinking ahead droning this pregnancy.
