Does anybody else have extremely painful stomach cramping with loose stool and increased urge?

Not sure if this is one of the big bugs that have been going around or if it's possibly food poisoning. Symptoms started on Tuesday. No body else in my family has any s/sx and the only difference in food intake was that I had pico de gallo at the wedding expo on Sunday. Went to the ER due to my BMS having bright red blood, waiting on cultures to come back but was sent home. I heard one person checking in with symptoms of cramping and bloody diarrhea.
