Feeling huge

Man, someone posted a pic of me today and I looked huge! Someone at work told me my face looked rounder. I'm 9w3d. I have been SO hungry 24/7 and want nothing but bad foods and snacks. I lost 35 lbs about 4 years ago and have kept it off. Pre pregnancy I ate meat, veggies, salads and some carbs. I can't even look at any of that right now. I know I'm growing a baby and I am sooo blessed to be able to do that, but I don't want to hate my body for the next 6 months because of excess weight gain. Maybe I should start light exercise? I'm just so tired. 😵😭
