9w with Bad Diarrhea, Stomach Cramps, & Chills

I’m a little over 9w pregnant with Baby #2. For the past few days, I’ve been having bad diarrhea preceded by stomach cramps and accompanied by chills... I don’t remember having this with my first. Is this normal first trimester G.I. upset, or might I be coming down with something?
