I am pregnant with my third child and with my first two pregnancies, I was sick throughout the first trimester. I was diagnosed with gluten intolerance (not developed into celiac yet) and have completely cut out all gluten. This pregnancy is soooo different. I have no nausea and think that it must be a result of my gluten free diet. It's the only thing that's changed in my life since the last two pregnancies. I think we're on to something!
