Hi. I am a 22 year old female. Have had an upset stomach on and off for the past 5 days now, and just today I started having diarrhea. Bad cramping, then Had to run to the bathroom a good 5 or 6 times at work. Then when I got home, the urgency continued, but now It reeeally feels like I need to go but all that comes is a lot of loud, kind of painful, gas and some brown/red jelly like substance..
