Bloody Diarrhea ?

I am 20 weeks pregnant and on 6/5/17 I caught a bug. I had a temperature of 101.8 and was constantly throwing up and had diarrhea. My fever finally went away last night including the throwing up but the diarrhea was still here. On top of that now my diarrhea is full of blood every time I go to the bathroom. Any ideas on what it could be?
