Feeling crappy today

Just don't feel good........ Stomach is not happy. I work in a kitchen it's always so super hot and I'm talking 100+ when we really get going and sometimes the heat just gets to me and today I feel so thirsty but I keep drinking water and now have water belly which doesn't help the just yuck feeling I have.....I wish this day was over! So I can go home about my feet up and relax, I'm only 7dpo so I'm sure that's not why I feel like this just one of those days I guess
