I know none of you are drs but I feel like crap and need an opinion. I got AF on Sunday and felt fine. Yesterday and today I feel horrible. I left work early today and tried to take a nap...still feel bad. I've had no appetite today. Now I have chills, vomiting, and diarrhea. I haven't had a cold so I didn't think it would be the flu but I haven't had the flu in years so I don't remember what it's like. Could it be AF?
