Food poisoning or just good ol pregnancy? Last night after work, I got really sick, not just puking. I haven't puked since 6 weeks along but during my dinner break I ate 20 mcnuggets. I think the Mickey ds did it honestly :/ I know a lot of you ladies work too but it's getting so hard for me and I stand for very long periods and get dizzy and have large amounts of prego brain which isn't good cause I count money. Is it different for everyone or am I just a weak person?
