Eating habits

Hi everyone I'm Veronica and I'm 6 weeks and a half pregnant. Ive noticed that my eating habits are not as good as it used to be before I got my BFP. I always been a gym rat, eating grilled chicken and sweet potatoes, with a no carb diet. Now , I can't stand to see a "healthy meal" . I been eating pizza for breakfast, burgers , pasta all day if I can and let me not forget sodas. So , I would like to know if any ladies out there have this "problem" .
