So hungry!!

I'm 34 weeks and I am constantly starving!! It's so frustrating. I eat protein with every meal and snack. I eat everything well balanced. I feel like I am eating all the time! It's probably a good thing I have gestational diabetes and have to wait two hours between meals or I would be a blimp! Odd thing is I have not gained any weight the past 3 weeks. But my baby girl is still growing!
