Anyone know what's up?

Out of nowhere I started cramping at work and sweating. I ended up vomiting 4 times in a row and by the time I made it home I threw up again followed by diarrhea (tmi sorry)

I'm having body pain and chills and a fever of 100.0

Is this maybe just a sudden flu?

Something I need to go in for?

I'm 21 weeks currently with my rainbow after my son was stillborn in September.
