weight keeps coming!!!

I'm stressing so hard!! I'm trying not to gain anymore weight during this pregnancy! I'm 8 months prego. And I seriously eat less and waaay healthier than my 3 year old son. Yet I gain weight as soon as I eat sumthing out of my diet...really making me sad. Btw I'm not just doing this for the hell of it. I'm already 10lbs over the doctors weight gain recomindation..what is going on!!😥😥
