Need advice!!!

Amber • Mommy to Bryce 12/2/14 & Myla 5/29/17. Expecting baby #3 December 2019!
I'm destined to be morbidly obese by the end of this pregnancy!!!!
​I work as a full time nanny/house manager/ personal chef for one family. Everyday I cook massive amounts of food & this family eats super healthy so everything I cook is organic, homemade, & fresh. I am just about 8 weeks & I'm finding all this healthy food revolting! The smell, the taste everything!! It's definitely bc I'm around it everyday. I never had an issue with any of it until recently! I love eating healthy for the most part, but ever since getting pregnant all I want is waffle fries smothered in cheese, pizza, grilled cheese (anything with cheese really)! I don't know what to do :( I want to be healthy for my growing bean but it makes me sick to my stomach!! Advice please!!!!
