plus size pregnant and self conscious

ladies so I'm currently 5 weeks pregnant 229 pounds 5'5with baby number 2 my first baby left me with that jiggly saggy belly at the bottom of my stomach and I'm just so self conscious its making me sad thinking that my belly is not just the baby but fat lol as stupid as it sounds it bothers me I wonder if im even going to look pregnant I decided to go with a nutritionist and eat right so I can feel better but I feel so bad when I want to eat something that I shouldn't but I really want and also just the fact that I may not loose weight kinda gets me upset. unfortunately my husband's family are so fast at pointing out how I look and how I can loose weight I just need some advice thank you for reading
