Hi, about 5 days ago I started gettin diarrhea and slight stomach cramps with an on and off pain on the left side of my stomach, a few days later I developed a cold but this is not bothering me at the moment, today I still hve the cramping, on and off pain, diarrhea, and I'm bloated, pressure inbetween my ribs and belly botton makes me feel sick. Then 20 mins ago I was sick, it was a dark purple colour and didn't have the usual 'sicky' after taste. Should I be worried? I cant get to see the doctor until tomorrow and am normally in good health.
