I'm not sure, it just kinda came on suddenly. Tonight I didn't even realize I was running a fever, but I took Tylenol again to see if I could calm the pain of the cramps and my fever broke. I'm all hot and sweaty now. It was this way yesterday and the day before, fever and stomach cramps. It's horrible :/ oh well.
i get diarrhea sometimes & get hot N cold flashes. and real bad aches in my abdomen too and than in my tailbone, also & im only 14 weeks.
but for you maybe it's jus something you ate, and its making you ill..
